Mitsubishi OT Iron Shaft Review

Mitsubishi OT Iron Shaft

MRCOTi Shaft

It is not often that we get to see truly new technology in the golf shaft business. The Mistubishi OTi series is something in my experience is truly new.

SheetWrappingLets start with the prepreg. Prepreg is typically the sheets of material, made of carbon fiber threads and resin, that are wrapped around a mandrel. The ‘sandwich’ is then wrapped with a retaining material, hung on a rack and baked. The cooked shaft is then unwrapped, the mandrel is pulled out and the process continues through sanding, trimming and finishing. The only exception I know of is AeroTech’s filament winding process.

MRCOTi_BradingMitsubishi Rayon has given us a new technology, braiding. it starts with a new form of prepreg they call Tow. The carbon fibers are arranged in bundles, the way a steel cable is made. The bundles are impregnated with resin and then woven into a braid. That braid bundle is then woven onto the mandrel. Yes, woven, I check on that. No spine. And the highest hoop strength I have seen on a graphite shaft. And given that heavy graphite hoop strength is lower than steel, the absolute lowest hoop strength in the business. The torque of all the models is about the same, 2.5 at the butt, 2.0 at the tip. Not as low as the same weight steel, but in the same range as other premium graphite iron shafts.

MRCOTi_EiHpTb

Radial consistency is off the charts, average 99.9% with a 0.1% standard deviation. I never thought I would see those kind of numbers. Shaft manufacturing technology is improving and new standards are being written. You can absolutely disregard shaft alignment with the Mitsubishi OT iron shaft. They are as round as I can measure round. If you are familiar with past Mitsubishi iron profiles, you will know these shafts. The Fubuki AXi family, one of my long time favorites no longer available is very close to this design. A Blue board like profile, a bit soft in the middle by design.

MRCOTi_FlightingThese are parallel design. I virtually trimmed the review profiles and found the design creates sets with very little flighting. This seems to be a trend in some of the recent parallel graphite shaft designs.

A benefit of carbon fiber parallel shafts is consistency within the set. Constant weigh shafts require multiple mandrels and multiple designs within the set to create consistency from shaft to shaft. They are essentially 8 different shafts and require both design and manufacturing integrity to deliver consistency within a set. This is not so with parallels. One mandrel, one manufacturing procedure. With reasonable attention to manufacturing processing it is easier to deliver consistent sets. Yes, there will be some weight loss and balance change as the shafts get shorter. But, one has to balance that against set consistency. And on that issue, from my recent observations, the jury is still out.

For those fitters and players that were familiar with the Fubuki AXi, the replacement has arrived. Go to the Mitsubishi OT expecting the same flighting. The review samples are getting tipped and heading to the range for feel testing.

Mitsubishi KuroKage XT Shaft Review

Mitsubishi KuroKage XT

KKXT_Image

The first version of this review was of a single shaft, others have arrived, prompting this update. There has been some buzz about the KuroKage XT. It quickly became popular on the PGA tour. Mitsubishi’s dealers have been snapping them up as soon as the shipments arrive.

TiNiThe KuroKage XT is another of the Mitsubishi shafts to incorporate highly elastic Titanium Nickel wire into the tip section of the shaft. The wire, shown here, is embedded into the prepreg and rolled into the tips section much like any other flag of prepreg would be.

In looking for a profile match, only Mitsubishi shafts were close. An interesting phenomena I never see. It hovers around the Diamana ‘ahina and the first generation Diamana white. The third generation Diamana White has moved on to a different design, which departs from the original profile. I see a variation on the ‘ahina. The flavor is there, the rough edges softened a bit, but if you were a fan of the original Diamana White Board or the second generation ‘ahina, you are going to like the KuroKage XT. The brittle hardness of the Diamana White and the ‘ahina have been softened by increasing the torque of the shafts. Yes, you heard that right, the overall GJ torque profile has been progressively increasing from the White to the ‘ahina and now to the KuroKage XT.

This video was shot at the 2015 PGA merchandise show. Meet Tsutomu Ibuki, the genius behind the Mitsubishi golf shafts. As we talk about this shaft late in the interview the feel of KuroKage XT design is discussed.

With the addition of the 60 gram shafts the consistency of the profiles in the model is confirmed.

KKXT_EiFsTb

The radial consistency averaged 99.5% with a 0.2% standard deviation. The most noticeable difference between the X and TX version was a change in butt stiffness and torque. There was not a lot of difference in weight, so one must assume the layup of the shaft was oriented toward torque. There is a lot of similiarity between the KuroKage XT TiNi and the KuroKage Silver TiNi. The difference being a tightening of tip stiffness. That tip stiffness can be seen in the above graphic.

KKXT_TorqueAs I mentioned earlier, the KuroKage XT looks like a Diamana White. Here it is compared to the first and second generation Diamana White designs. The bend profile signatures are almost identical. The torque profiles INCREASE. This can only be the result of tour feedback. This is an evolution of design. Elastic Titanium Nickel wire in the tip and higher density graphite fiber. Player feedback is about feel, and we know that one way to get feel into a shaft is to add a little torque. Not much, but just enough to get the approval of the tour pros the Mitsubishi team works with.

Mitsubishi Diamana Thump Fairway Review

Mitsubishi Diamana Thump Fairway

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter
Fit2Score, Dallas Fort Worth, Texas


The Diamana Thump name has been used before in a line of iron shafts and in a hybrid shaft. The irons have been discontinued. The Diamana Thump Hybrid is still available, now a special order item. It is my all time favorite Hybrid shaft and has been in my bag for a very, very long time. When I saw the name thump applied to a fairway shaft I had high expectations, and the measurements of this shaft met them. Mitsubishi discontinued the Fubuki AX Fairway shaft in 2014. It occupied a unique niche, a fairway only shaft, 43″ long uncut, at $250 MSRP, with all the unique qualities of the premium Mitsubishi $400 driver shafts. The Diamana Thump Fairway once again fills this niche. At $250 it puts delivers premium quality at a more approachable price point.

As I worked my way through the measurement of this shaft I left torque for last. Everything looked very good, would the torque be low enough to compete with the premium Diamana’s I have been using in custom fitted fairways. The answer, yes. Tip zone torques of 2.3 in the 70 and 80 gram versions put it into that special class of shafts that can comfortably control the extra weight of a fairway and maintain club head alignment during a preimpact brush with the turf.

Fairway_Diamana_Thump_EiTb
Radial quality of the review samples was 99.6% with a 0.4% standard deviation. Translation: shafts don’t get any rounder, don’t bother with alignment and use this shaft without reservation in a rotating hosel fairway head. Look again at those torque numbers. This is a high launch design, something most of us want in our fairways. The typical shaft that delivers high launch is also high torque. If the stock shaft in your fairway has a tendency to create hooks when you lean on it, you should consider replacing it with the Diamana Thump Fairway. Replacing your stock fairway shaft with the Diamana Thump will create a club you can trust.Fairway_Diamana_MyFavorites

I have built countless numbers of custom fit fairway metals with the Diamama Red and the KuroKage Proto TiNi driver shafts. They launch high, with adequate spin to deliver drop and stop shots. The Diamama Thump Fairway, at about 60% of the price, has a very similar design. It is a bit stiffer in the butt section which for those with an abrupt transition is a good thing. The profile of these shaft from high mid to tip is hard to tell apart. And they all sit in the same torque range. The Thump Fairway and the KuroKage Tour Proto TiNi have much the same hoop strength.

Check back, the Club Conex UniFit tips are installed and the Mitsubishi Diamana Fairway Thumps will be range tested soon.

Diamana D+ & Diamana S+ Driver Shaft Review

Mitsubishi Diamana S+ & D+ Driver Shafts – 2015

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter

Diamana Blue S+ Driver

915d2-driver
The stock shafts in the 2015 Titleist 915 drivers include the Diamana Red, White and Blue models. This year, unlike last year, they have the same appearance as the original Diamana shafts, a silver background with the Red, White or Blue Diamana logo. And, with the exception of a very slight increase in torque, they are identical to the legacy design.  We have received review samples of the Blue and a few of the Whites. The remainder of the Whites and the Reds will be added to this review when they arrive.

The Blue Diamana is perhaps the most copied driver shaft design I have ever seen. It is a good fit for golfers with a quick swing and a hard transition. The profile has a soft mid in relation to the tip and butt. The Diamana + models are available as options from most companies in 2015. Many, at no upcharge.

MRCDiamanaBlueS+_EiGjTb

The average radial consistency of the review samples was 99.4 with a 0.3% standard deviation. Such numbers were not seen a few years ago, especially in stock shafts. The lighter weight models have slightly softer tips, with the tip stiffness increasing in the heavier models. The 60 gram models are in the Titleist 915 Stock drivers and the 70 gram versions in the Titleist 915 Fairways. You can find these in most retail fitting carts. The Diamana feel is unique. A good way to describe it is to clap your hands flat against each other, then again with them cupped. The Diamana feel is the thump you get from the cupped hand clap. It is addicting, and you will know by the sweetness of that feel when you struck the center face.

Diamana White D+ Driver

MRCDiamanaWhiteD+

The 2015 Diamana D+ resembles the Diamana White board is more than just looks. With the exception of 0.4 degrees of higher torque it is hard to tell them apart. If you have ever played the original Diamana White or the second Generation ‘ahina you will know this shaft.  It defines low launch, low spin design. Unless you have a positive angle of attach, stay away from this shaft. If you do, it is made for you.

MRCDiamanaWhiteD+_EiGjTbThe full set of weights and stiffness samples have yet to be arrive, this is what I have for now, The average radial consistency of the 4 review samples was 99.6 with a 0.1% standard deviation. That is beyond outstanding for a shaft made primarily for stock golf clubs. Mitsubishi sets a quality standard that others must follow. Why should you expect anything less in a $500 driver from Titleist? Why would a manufacturer compromise the play ability of their products with off spec shafts? The 915 drivers from Titleist are delivered with outstanding shafts.

Diamama Red Golf Shaft Review

Mitsubishi Diamana R – Third Generation

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter
Fit2Score, Dallas Fort Worth, Texas

Diamana3Gen_R_Image

The last of the third Generation Mitsubshi Diamana driver shafts released in September 2014. The Diamana ilima, the second generation Diamana Red Board has long been my favorite fairway shafts. The expression, ‘if its not broken don’t fix it, applies the the third generation Diamana R. It changes very little over the second generation design. The butt stiffness is a little softer, allowing for a little more load at the start of the downswing. New material, high modulus 80 ton fiber is use in the hoop wraps in the shaft. In the butt, the hoop strength increases while the stiffness decreases. We are seeing more creative designs in carbon fiber golf shafts. Design is limited by the creativity of the shaft engineer and by the willingness of the golfing public to embrace these new products at ever increasing costs. At $400, the Diamana R, one of the greatest fairway shafts I know of, is beyond the typical $300 price of the off the rack fairway. You get what you pay for, and in this case, in the 70 and 80 gram models, you are paying for tip torque low enough to control the weight of a 3 wood head.

This is a high launch shaft. For those who hit their woods off the turf, where a downward angle of attack is all that is possible, a high launch shaft is a good thing. With a driver, and an upward angle of attack we would seek a lower launching design. But with a fairway, this is my design of choice.

MRC_DiamanaR_TbGr3gMDI

I checked 10 shafts, one of each weight and flex, the average radial consistency was 99.6% with a standard deviation of 0.2%. That is an example of the made in Japan tradition of excellence we have historically seen from Mitsubishi Rayon. This is the first shaft I know of to use 80 ton material. It is too stiff to be used in the linear and bias plies. It is used to create hoop strength. Because it is thin and has no open space like multi axis weaves it creates high hoop strength while leaving the shaft designer the space inside the multi layered wall to achieve the linear and torsional strengths he is seeking to achieve. All while creating a smooth lose of stiffness down the shaft and the unique Mitsubishi feel.

New to third generation Diamana R series are 50 gram shafts. The line between the ultra light driver shafts and light weight versions of standard shafts is getting blurry. The Diamana R series extends the profiles consistently into the 50 gram versions. Those with slower drive swing speeds that need launch and spin can get it without having to accept a high torque tip.

Now that the third generation Diamana release is complete, lets compare the three designs by looking at the 60 gram version of each shaft.

Diamana3Gen_60_RWBThese shafts are not as different as they once were. At least in the 60 gram versions. The Diamana B series was reviewed earlier as was the Diamana W. The profile of the Diamana W changes significantly in the 70 and 80 gram versions. But as you can see here, in the 60 gram version is it just a little higher launching than the Diamana W. The Diamana R is a different shaft. Softer handle, quicker loss of stiffness from mid to tip. All three shafts get stiffer as they approach the tip. If I want a stiffer shaft, I will always simply change to the next step on the stiffness progression, either getting the heavier of the stiffer model before I would consider tipping these shafts.

Mitsubishi KuroKage Tour Edition TINI Driver Shaft Review

Mitsubishi KuroKage Proto TINI Driver

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter
Fit2Score, Dallas Fort Worth, Texas

MRC_KuroKage_Tour

The KuroKage Proto TiNi is available only through selected Mitsubishi dealers. I briefly covered this shaft in an earlier review and did not give it the attention it deserves. It is currently in the driver of the #1 player on the PGA tour. His shaft is a custom made version, beyond the 7-XX available to Mistubishi dealers. My friend Biv Wadden has me continuously building drivers for his students with this shaft. When you have as many shafts as I do in my fitting system, some go unnoticed as I tend to fit what I know. Biv’s praise of this shaft got me to take a closer look and start testing the shaft myself.

“For the past year, I’ve been putting most of my competitive students into the KuroKage prototype tour edition shaft with its nickel-titanium tip – in both drivers and 3-woods. It consistently produces higher ball speeds and lower dispersion than any other premium shaft I use.”
Biv Wadden

The result, the Diamana ilima’s, which have had a 3 year run in my fairways have been replaced with KuroKage Proto’s. With a $400 price tag this is not likely to become a best seller. Unless of course you try it and it fits your swing. Here is a look at the shaft measurements from the latest version of the Fit2Score knowledge-base.

MRC__KuroKageProto_EiTBTbRadial integrity of the samples was 99.5% with a 0.3% standard deviation, excellent. Hoop strength was a little lower on the handle end of the 60 gram shafts. The balance is high like most driver shafts now being produced. The profile shows a soft handle, moderate mid, stiff tip design, with a maximum bend in the 14″ region. The lower 12″ of the shaft is wrapped with Titanium Nickel Wire touted by Mitsubishi as able to stretch then immediately regain its original shape. This material is used in the KuroKage Silver, but the Proto has a longer section of the impregnated with the TiNi wire. While both shafts incorporate the TiNi wire, the profiles are about as different as MRC profiles get.

The KuroKage Proto was the first of the heavier shafts to incorporate the TiNi wire that had been used in UltraLight Bassara series of shafts. It was also the first to use 40 ton fiber. Mitsubishi Rayon is now using 80 ton fiber in the hoop layers of the third generation Diamana’s. The Bassara UltraLite Phoenix, released in 2014 is a light weight version of this profile. It adds the lighter weights not offered in the KuroKage Tour Edition shaft.

The profile is very similar to the Diamana ilima. The butt a little stiffer the tip a little softer. It launched much the same for my swing with a little less spin, creating a more boring flight. The 70-XX in the hands of the +110 kids is delivering tight dispersion, with good trajectory and a little lower spin than would be expected for the launch. And that combination, as Biv tells me, equates to distance.

 

Mitsubishi Fubuki J Golf Shaft

Mitsubishi Fubuki J Driver Shaft

MRC_FubukiJ_Image
The fourth generation Fubuki, the Fubuki J, released to Mistubishi Golf Club Fitters in June of 2014. It is an update of the second generation Fubuki, the Fubuki Alpha. I see the Fubuki family as two different profiles and discussed them in an earlier article. Here is a quick overview of the two profiles.

MRC_Fubuki_TourvsK The original Fubuki Tour and the Fubuki K,introduced a few years later, are very much like the Diamana White and the second generation White, the ‘ahina. The third generation White, the Diamana ‘W” series is a different profile. The Fubuki Tour was discontinued in 2014. The Fubuki K is still in the product line.
MRC_Fubuki_AvsJThe second generation Fubuki Alpha and the fourth generation Fubuki J are also the same profile. They similar yet subtly different than the Diamana ‘ilima and the KuroKage Proto TINI. The differences make these unique designs that must be tested to find your best fit.

 

MRC_Fubuki_J_EiGjTbOn yet another shaft, the radial quality is close to perfect, the soft plane average is 99.5% of the hard plane with a standard deviation in my sample of 0.2%. Alignment of this shaft is meaningless. And on another design, we see a section near the tip that gets stiffer to closer we get to the tip. Tipping this shaft would be cutting away some of the stiffness designed into the shaft. The bend profiles of the entire model line, from 50 gram to 80 gram are the same. Stiffness is a function of weight. Every Fubuki J shaft has the same bend profile.

FubukiJ_tsubaThe Fubuki J is counter balanced, the balance point is close to 3 inches above center. Mitsubishi tells us this is similar to the handle weight of a sword as illustrated. This is done by adding tungsten powder to the prepreg used in the handle of the shaft. While we see some additional stiffness in the handle, this is by design. It is not caused by adding wall thickness to create a counter weighted shaft. Adding wall thickness to the butt is a common design in high balance shafts resulting in handles with damped feel. The handle section is also reinforced with a metal mesh sheet, controlling deformation (ovaling) without affecting bending.

FubukiJ_tipThe really interesting technology of the Fubuki J is the tip. I am again going to share with you in illustration from the Mitsubishi dealer publication. The tip is a combination of low torque zone close to the hosel with a softer section just above it to create a hinge. I am going to repeat myself, don’t think you are going to stiffen this shaft by tipping it. You will be cutting away some of the engineered design. Get a stiffer shaft.

The first time I hit this shaft the tip stability got my attention. I felt stability during impact I have never felt before in a golf shaft. I do not hit the center of the face as consistently as our regular shaft testers. The Fubjki J gaves me head stability on my toe and heal strikes. It knocked the Diamana B out of my bag. Now after two weeks and multiple rounds of golf, unlike many other first loves, it is still in the bag. There are many shafts that claim high launch, low spin. The Fubuki J in my hands actually delivered on the promise. Here is a quick look at my FlightScope summary comparing the 50 gram X flex Fubuki J and the same weight and flex Diamana B in a 10.5 Adams XTD ti driver head set to 11.5 degrees.

FlightScopeReport_FJvsDBWhy would someone with a 93 MPH club head speed be concerned with spin. Not shown in this table is my -3.5 degree angle of attack. That negative angle of attack delofts my head at impact and adds spin. The Fubuki J added loft and reduced spin. The ball is up and the spin is down, keeping me from ballooning drives into the Texas breeze. When life gives you lemons, make lemonade. I have been struggling with that negative angle of attack and have not yet found my personal motion get to correct it. Until I do, the Fubuki J is my gamer.

Mitsubishi Bassara Phoenix UltraLite Driver Shaft

Bassara_Phoenix_Image

In 2013, Mitsubishi Rayon began the introduction of shafts that are available only from Authorized Mitsubishi ClubFitters. The UltraLight Bassara Phoenix released in 2014, is the third such shaft.. The color is dramatic, a burnt orange with a clear coat finish. The bend profile is a perfect match to the KuroKage Proto TINI, the first of the fitter only shafts. That profile is one of my favorites for a well trained swing. TINI stands for Titanium Nickel Wire. It was first use in the Ultralight Bassara “G” series shafts. It is now being added to many shafts. It is a high elastic material that can stretch and immediately regain its original shape. In addition to storing and releasing energy, it stabilizes the shaft tip.

TINI_illustrationTip stability results in tight dispersion. A consistent loss of stiffness makes this profile easy to load and many find it adds dramatic distance to their drives. The KuroKage Proto TINI is only available in 5 models ranging from 60S to 70XX. The Bassara Phoenix completes the range, starting with a  30 gram L flex and ascending to a 59 gram TS flex.

Bassara_Phoenix_EiGjTb

The radial consistency is excellent, averaging 99.4% with a 0.3% standard deviation. If we look for similar designs in iron shafts, the KBS Tour is the closest bend profile design. Both have a consistent loss of stiffness from butt to tip, Near the tip, the stiffness increases to stablize the head during impact. With such designs, tipping will actually remove some of the tip stiffness. With the Bassara Phoenix, if you want more stiffness, get a heavier, stiffer shaft. Tipping is not recommended for this shaft. Alignment of the Phoenix is not necessary nor will it be beneficial. The radial consistency of the Phoenix makes it excellent for rotating hosels.
Bassaras_EiGjA comparison of the current Bassara UltraLight models shows the Phoenix and the Wyvern to be quite similar. The Phoenix profile indicates a little more launch. The Phoenix is modeled after the ilima profile. In fitting after fitting, I put more ilima’s into fairways metals than all other shafts combined. The 53TS Bassara Phoenix is a great shaft if you are looking to build an ultralight fairway.

MRC_KuroKageBlue_Image

In 2014 Mitsubishi reintroduced the Bassara V shaft as the dealer only KuroKage. It is a great looking shaft, Blue ion finished. It has a great history, this was Lorena Ochoa’s shaft. Many years ago I fit a great many of these. It is a Diamana Blue with about a half degree more torque. The radial consistency of all the samples measured was 99.6% with a 0.3% standard deviation. Translation, excellent. Install this shaft in any orientation, use it in a rotating hosel. Shaft to shaft consistency; as good as it gets, the fitter and the shaft your club gets built with will be indistinguishable from each other.

MRC_KuroKageBlue_EiGjTbIf you are familiar with the Misubishi Blue Board design, you know this shaft. In a former life it looked like this:

MRC_BassaraV_ImageSome of the shafts I measured for this review came from the fitters that were still in my shop. I was impressed that many years ago when this shaft was first available that the radial quality was exceptional.

 

Mitsubishi Fubuki Z and Fubuki ZT Golf Shaft Review

Mitsubishi Fubuki Zeta & Fubuki Zeta Tour Driver Golf Shafts
Callaway Big Bertha 2014 Stock Driver Shafts

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter
Fit2Score, Dallas Fort Worth, Texas

Fubuki Z

FubukiZ_Image

Several years ago Mitsubishi Rayon began making high quality shaft models for the golf club manufacturers. These designs closely resemble the Mitsubishi Rayon premium shafts. The Fubuki Zeta and Fubuki Zeta Tour continue this tradition. The driver market has settled in on a $400 price point and most premium shafts range from $300 to $850.  For some, these prices are justified by performance, for others, they are not.

drivers-2014-big-berthaThe 2014 Callaway Big Bertha stock shaft is the Fubuki Zeta or simply Fubuki Z. For those that are familiar with Mitsubishi Rayon golf shafts, the shaft design is indicated by the little letter that is left of the weight. The Fubuki Z is indeed a quality shaft, it is just not made in the Mitsubishi Japanese facility. While many of the great shafts of the highest quality are made in Japan, other production facilities around the world are capable of the same level of quality. And many have put in place stringent quality control standards that assure only quality products go out the door. What I have measured in the review samples of the Fubuki Z and ZT indicate this is certainly true on this line of shafts. Radial consistency of the Fubuki Z was 98.8% with a 0.7% standard deviation and 99.4% with a 0.4% standard deviation for the Fubuki ZT. These are outstanding numbers as they should be for a shaft offered in a driver with a rotating hosel. Shaft alignment is not a concern with these shafts. Shaft to shaft consistency is not the same as the awesome quality seen in the Mitsubishi Japan productions, but it is respectable.

FubukiZ_EiGJTbThe Fubuki Z looks to me much like the Fubuki Alpha. The Fubuki series has been around for quite some time, starting with the Fubuki Tour, then the Fubuki Alpha and most recently the Fubuki K. I have a lot of experience fitting the Alpha. It launches a litter higher than average with a bit more spin. The difference between the Fubuki Zeta and the Alpha is torque. The Fubuki Zeta has about a half degree more torque through out the shaft than the premium Fubuki Alpha. If you demo the Fubuki Zeta and think a little tighter dispersion will come from tighter torque, the Fubuki Alpha is available as a $150 upgrade from Callaway.

Fubuki ZT

FubukiZT_Image

drivers-2014-big-bertha-alphaThe Fubuki Zeta Tour is the stock shaft in the 2014 Callaway Big Bertha Alpha. The profile is similar to the Fubuki Z. The balance point is shifted upward slightly allowing for swing weigh to be maintained with a heavier head. Other than the balance shaft, there is very little difference between the Fubuki Z and ZT. Both are available and interchangeable in a Callaway fitting cart.

An interesting $150 upgrade option from Callaway is the Fubuki K. The Fubuki K resembles the Diamana W series, with a mid shaft stiffness bump creating a lower launch lower spin ball flight.

FubukiZT_EiGJTb
