Graphite Design Tour AD SuperLite Driver Shaft Review

Graphite Design Tour AD SLII Driver Shaft

GD_TourAD_SLII_ImageGraphite Design added a light weight shaft to the popular Tour AD Line in 2014. This shaft, like many others in the light weight category, ranges from 50g to 60g, with stiffness corresponding to weight. In this weight range, we see higher torques, but not so high that I would be concerned about head stability. These shafts are designed for swing speeds in the 60 to 85 mile per hour range. The 60g SR flex extends to the 90 mph range. My swing speed in in the high 90’s with the occasional 102 showing up and I am playing an ultra premium 59g shaft. Light weight driver shafts, made out of high quality carbon fiber are the future of golf for many of us. That couple of grams I lost in my latest shaft change has given me a new range of control and feeling without any increase in dispersion. In fact, I am hitting more fairways than I ever have now that I changed to a sub 60g shaft.
GD_TourAD_SLII_EiTBGjFsHpTbRadial integrity of the Graphite Design Tour AD SLII is exceptional, the review samples averaged 98.5% with a 0.4% standard deviation. The hoop strength is high for this weight range, and distinctly different in the 4 vs 5 models. This measurement is new for my knowledge base.

This is a unique design, there is no close match in the database. The tip to butt ratio and the tip load and butt load deflection analysis shows it to be a high launch high spin design consistent with what Graphite Design is saying about the shaft. In the speed range it is designed for, that is what will optimize distance. Tip torque is tight. Butt torque is in the range that transmits adequate feel in light weight shafts. If your swing speed is below 90 mph and you are looking for a quality shaft this is one you should be testing.

Mitsubishi Bassara Phoenix UltraLite Driver Shaft

Mitsubishi Bassara P UltraLite Driver Shaft

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.


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.

True Temper Project X PXV 39 Golf Shaft Review

True Temper Project X PXV 39 Driver Shaft

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

TTPX PXv39 ImageI have seen fair number of driver shafts with labels implying light weights, but I have only seen one shaft that was labeled with a number that actually was the weight of the raw 46″ shaft. The True Temper Project X PXv 39 is correctly labeled. The raw shaft is 39 grams. It is like holding a feather in your hands. When I start measuring a shaft I usually start with the EI profiles. With the Project X PXv 39 I started with radial quality. Surely a shaft this light was likely to have a low number. The number was shocking, the review samples were close to perfect. If you are going to make a shaft with walls as thin as they are on the PXv 39, they need to be perfect. This is a 39 gram shaft that can be oriented in any direction in a rotating hosel. It is the light weight version of the Project X PXv family of shafts.

While the torque numbers at first glance look high, they are as low as I see in shafts of this weight. I would not be putting this shaft in the hands of an aggressive high speed ball striker. However, at 6.4 to 7.0 pounds of butt stiffness, these are not wimpy shafts.

TTPX EIGjTb PXv39The bend profile is not uncommon for shafts in this weight range. I have had a lot of success fitting a similar profile in this weight range. The quick decline in stiffness in the high mid area, combined with a long stable tip section results in the launch needed in this weight range with good dispersion control. I am seeing this design in a number of high performance golf shafts.

TTPX PXv39 TipI have heard shaft designers discuss the weight of paint on ultralight driver shafts. There is no elegant glossy overcoat on the Project X PXv 39, every possible aspect of weight control went into this design. It is available only through True Temper Performance Fitting Centers. One look at the wall thickness of the tip and you will quickly realize this shaft should be installed by a competent club builder. High modulus carbon fiber are making designs possible that could not be considered a few years ago. The Project X PXv 39 is one such design.

Miyazaki B.Asha Golf Shaft Review


By Tony Curro
Tru-Fit Custom Clubfitters, Latham, NY


Miyazaki released the B Asha Series of shafts in 2013 as an upgrade to the popular C.Kua line.  This line of shafts offers a lightweight shaft with incredible stability.  The 3R and 3S models come in a .350 tip.  The rest of the line has the traditional .335 tips.  The brown logo artwork which is a trademark of Miyazaki really stands out on the white background of this shaft.  The handsome graphics are original artwork painted specifically for the B Asha line of golf shafts.

MiyazakiFlexCodeMiyazaki Golf shafts are labeled according to an international flex code.  This code give a four digit number which explains the level of flex in each of the 4 regions of the shaft.  These regions are the Butt, Mid-Butt, Mid-Tip, and Tip.  Each of these regions are rated on a scale of 0-9 with 0 being the most flexible, and 9 being the stiffest.  A shaft code of 9842 would have an extremely stiff butt and Mid-butt region, and mid stiffness through the mid-tip region and a flexible tip.   These flex-codes help fitters match the bend profile of a shaft to a specific golfer type, or desired ball flight. The B.Asha Line of Miyazaki shafts varies in range from 46-48 grams in the 3 series, to 54 grams in the 4 series, 61 in the 5 series, and 75 in the 7S.  These are the lightest shafts that Miyazaki offers, and are ideal for Ladies and Seniors.  These lighter weights are ideal for golfers looking for a higher launch without sacrificing distance. In the B.Asha model, the torques of these lighter weight shafts were reduced from the C.Kua. editor Russ Ryden got to talk to Tim Gilles, Director of Sales for Miyazaki Golf Shafts at the 2013 PGA Merchandise show in Orlando. Part of that discussion covered the changes made to the Miyazaki B.Asha Golf shaft.

Looking at the bend profile of these shafts, they promote an active tip, especially in the 3R and 3S models.  Again, these are .350 tips, and do provide a stable tip section despite their super-lite weight characteristics.  The tip action promotes higher launch conditions without ballooning.  The 3 series maintain their flexible characteristics through the mid-tip, Mid-Butt and through the butt sections.  The international flex codes for the 3R (4222), and 3S (5433) models indeed give these shafts much more action in the tip and mid-tip sections.  In our range testing sessions, these shafts indeed launch the ball higher, but not at the expense of spin rates that were off the charts.  The higher launch coupled with lower spin rates from comparable shafts give these shafts a huge advantage in maximizing distance. We have found that the 3A and 3R shafts are ideal for Women and Senior’s who are slower swinging golfers looking to max out their distance.



The 4 series promote a stiffer mid-butt and butt section, with an active Mid-tip and tip region.  The flex codes for the 4A thru X series are as follows:  A(3411), R(5621), S(6732), X(7854).  The 4 series varies in weight from 47g to 53g and is ideal for golfers looking for a lightweight shaft that really launches the ball.  In range testing, these lighter weight shafts proved beneficial to golfers who have smoother transitions to the ball.  The Lower to mid stiffness rating in the A and R models coupled with higher torque in the Butt section and tip give the golfer plenty of feel in this lightweight model.  In Range testing, the model proved true to form.  Golfers really benefited from the softer feel of these shafts, resulting in more consistency off the tee.  Golfers with higher swing speeds who were looking for higher launch conditions seemed to really benefit from the stiffer models.

The 5 and 7 series are meant for golfers who have higher swing speeds looking to maximize ball Speeds off the tee.  The Stiffest models 5X and 7X have flexion codes of 7785.  These shafts maintain stiffness through the mid-tip region allowing for an extremely stable shaft that enables a higher launch with lower spin.  Range testing has verified this and golfers tested felt that the stability these heavier/stiffer models allowed them to” lean on it”, without feeling they were losing the shaft at the top.  On average, the golfers tested gained 15+ yards in distance without sacrificing dispersion.  That is huge when explaining the difference in a stable aftermarket shaft.


Miyazaki has hit a virtual home run with their newest line of shafts.  The handsome graphics and colors really stand out, without being over the top.  From a performance standpoint, they do as advertised,

Project X Driver Shaft Review

True Temper Project X & Project X PXv Driver Shafts

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

The Project X brand name came from Royal Precision. Royal Precision, an iron shaft only company, was acquired by True Temper in 2006. The Project X brand name was part of that purchase. Project X branded driver shafts appeared soon after that purchase.  They use the same stiffness designation as the Project X irons shafts, numbers, rather than letters.  The 5.0, 5.5, 6.0, 6.5 & 7.0 numbers designate stiffness.  The original numbering scheme was formula based and came from frequency and length.  The numbering system on the Project X driver shafts, like all other driver shaft stiffness designations I have seen are based on both weight and stiffness.  A heavier 6.0 shaft will also be a stiffer 6,0 shaft.

TTPX Composite Ei.fwI looked at four versions of the Project X driver shaft, the original Blue, the lighter weight Black, the newer, PXV Tour52 and the PXV. The profiles are compared in this chart. With the exception of the PXV Tour52, the bend profiles are quite similar. The nearest match my software located was the Graphite Design TourAD BB. The Project X has about .6 degrees more torque than the Graphite Design TourAD BB. You can expect a lower than average launch from the Project X driver shafts.

Project X Blue Driver ShaftTTPX Image PX Blue.fw

This shaft has been with us for a few years.  In the 6.5 model, stiffness is added to the tip. The slight bump seen in the average chart is an indication of that stiffness showing up in the averages. Radial quality is excellent, meaning alignment if the Project X family of driver shafts will not matter. TTPX EIGjTt Blue.fw

Project X Black Driver ShaftTTPX Image PX Black.fw

The original Project X blue was lightened ever so slightly in the Project X Black version.  And, as you can see, the tip was softened to create a higher flight. Quality is excellent, All weights and flexes follow the same bend profile design.TTPX EIGjTt Black.fw

Project X PXv Tour 52

TTPX Image tour52PXV.fw
The PXv Tour52 is a different shaft. In a light weight shafts, this profile is a low launch design. The traditional concept of the Project X was low launch and looking at this profile, I can see a design that honors that tradition. In this weight range, the torque numbers are quite low.  Typically as weight goes down, torque goes up, not so with the Project X PXv Tour 52.
TTPX EIGjTt Tour52 PXv.fw

Project X PXvTTPX Image PXV.fw

The Project X PXv is very similar to the original Project X Blue. The tip is a little tighter and stiffer. It makes sense to not make big changes to something that works. As with many revisions, the graphics get updated, and small changes, typically the result of upgrades in carbon fiber material, address tour feedback. Once again, in the stiffer versions, there is a low mid stiffness bump to give the stronger player tip stability.

UST Mamiya ATTAS3 and ATTAS4u Golf Driver Shaft Review


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

TourSPXTransparetLogo.fwThe UST ATTAS3 and ATTAS4u driver shafts are ultra premium models made from ultra-high modulus, low resin content materials. This is the trend in professional quality driver shafts. The material cost and the price of this class of golf shafts is well beyond the retail price of stock drivers.  The MSRP on these shafts is $560, they are only available from UST TourSPX dealers. At this price, you would not want to invest in a shaft that had not been tested with your swing by a professional, launch monitor equipped fitter.


USTMamiya ATTAS4u ImageUSTMamiya ATTAS4u EiGj

The model number, 5, 6, 7 & 8 accurately represent the weight of the shafts when cut to installed lengths. The balance points ranged from 24″ to 25″ not putting these into the category of counterweighted designs. Torques measured in the same range as the UST VTS Silver, marking this as a mid torque design. When I use that term, I am discussing torque in the range found in ultra premium golf shafts. That range is entirely different from what is typically found in off the rack golf clubs. Off the rack driver shafts start beyond what is found at the high end of the range of tour quality driver golf shafts.

The measurements of the ATTAS4u revealed two distinct profile patterns. The ultra-lite 5 is a different design than the rest of the models.  This is not an uncommon practice.  Ultra-lite shafts are used by a different swing speeds and styles. They should fit that style and the manufacturers are wise enough to model the designs to the player most likely to use them.  This shaft features a stiff mid, found by UST research to control dispersion.  Our testing found it to me a mid launching design with slightly lower spin than the companion ATTAS3.


USTMamiya ATTAS3 ImagecUSTMamiya ATTAS3 EiGj

The UST Mamiya ATTAS3 looks like a sibling of the ATTAS4u, the graphics are identical, only the color changed. Torque values are about one half a degree higher through the model when compared to the ATTAS4u.  We see multiple designs in the different weights. The ATTAS3 4 model is the first from UST in a premium ultra-lite driver shaft. The raw shafts weighted 48 grams, putting them around 45 grams installed. In this weight range, tip and butt torques of 3.1 and 5.1 set a new standard. This can only be accomplished with high modulus graphite fiber.

Balance points are the same as the ATTAS4u. It should be noted that the radial quality of these shafts is outstanding. Several of the review samples showed NO difference between hard and soft plane stiffness. At this price, one would expect no less. These shafts ooze quality.

USTMamiya ATTAS 34u7X.fwWe took the 7X versions to the range for testing by Mark Maness, Mark will be one of our shaft testers in future reviews. Mark was a PGA Tour member in 1988 competing in 28 events including the US Open. He is the Director of Golf Instruction at the Golden Bear Golf Center in Carrollton, Texas. Mark is a PGA Class A instructor and active in the North Texas PGA chapter.

USTMamiya ATTAS3 impact

We use Markit spray on the golf club face to document the impact pattern. High and low strikes will influence the launch and loft of the ball flight. A driver face rolls from top to bottom, changing loft as it does so. Most testing is done with a robot to get consistent ball strikes on the center of the club face. Mark Maness is every bit as good as a golf robot.  He has the additional advantage of being able to describe the feel, balance and responsiveness of the golf shaft he is testing.  The image shown above documents his 7 strikes with the UST Mamiya ATTAS3 7x.  As you can see, one was a little high, one was a little low, but the other 5 were dead center. Mark Maness, our own living and breathing ‘iron byron’.

FlightScope Reports

USTMamiya ATTAS4u TRA review of the best 5 of 7 strikes using range balls with a 45 degree left to right cross wind, coming  into Mark’s face shows a slightly lower launch lower spin from the ATTAS4u compared to the ATTAS3. This is consistent with what I was told to expect from the UST Mamiya fitter/tester at their Fort Worth US Headquarters.  Mark’s comments:
ATTAS4u “I feel a soft tip, my rhythm is too quick for this shaft, it would be a great shaft for a slower tempo swing”
ATTAS3 “I like the feeling I am getting from the tip. The weight of the club feels centered, that is how I sense the shaft loading.  I can feel it load from the center”

Remember when looking at these results, this is one golfers fit. Everyone interacts differently to these profiles and the only way to find the right shaft for your swing is with a professional fitter that understands golf shafts and is equipped with a wide range of shaft fitting options.

Aldila 44 Magnum Golf Shaft Review


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


The Aldila 44 Magnum is the first ultralite driver shaft from Aldila.  Fitter take note, the R & S profiles are different from the X and Tour X.  When I look at the specs on the R& S verions, I see a shaft I used to love, the Mitsubishi Bassara Hawk which was a light weight Diamana White Board.  The Magnum 44 torque for the R & S is however 1.5 degrees more than the Hawk.  You can expect a low launch when properly fit.  If you like light weight shafts, and over power them, this will move to a boring mid launch trajectory.  Those higher torque numbers are a concern if you over power these softer flex versions.

The X and Tour X versions have some additonal stiffness in the tip area, and butt torque at 4.8 and 4.3.  With 3.3 and 3.1 tip torque, These are respectable numbers in a 49 gram shaft.  I am planning some range testing on a stack of light weight shafts that have been accumulating.  Radial quality is excellent, the shafts are suitable for rotating hosels.

Mitsubishi Bassara Golf Shaft Review


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

Mitsubishi Bassara UltraLite Series W

Bassara Series W
The lightweight Bassara Wyvren was introduced in 2011. Like the Griffin, it has elastic titanium fiber reinforcing the tip. It has a unique color scheme, resembling the Griffin. It is appropriately red, Bassara W-Series, as it is now called, profile is the same as the ‘ilima. Look for a high launch with low spin from this shaft. The golf shaft is now referred to as the Bassara Series W. The shaft to shaft consistency and smoothness of the profile is among the best I have measured. The overall torque of the Bassara W-Series ranges from 6.1 in the 43L to 4.3 in the 53TS. This is consistent with the general torque range of the Mitsubishi Rayon Family of shafts if one compares the torque of the 53 Bassara W-Series with the 60g R’s of the other products. Three and four degree TIP torques are outstanding in this weight range of shafts.
Bassara W EiGj

Mitsubishi Bassara UltraLite Series G

Bassara Series G
The lightweight Bassara Griffin is unique. Introduced in 2010, it has elastic titanium fiber reinforcing the tip. Mitsubishi is unique in the shaft business; they make all the critical shaft raw materials, monomer, acrylic fiber, carbon fiber, resin and prepreg. When they decide to make a unique product, they have few restrictions. The Griffin is one such product. In the hands of a slow swinging, yet skilled golfer this shaft delivers the head consistently. Originally branded as the Griffin, it is now referred to as the Bassara G. It is the higher launching, higher spinning design of the 2012 Mitsubishi ultra lightweight driver shafts The overall torque of the G -Series ranges from 5.6 in the 43L to 4.0 in the 53TS. This is consistent with the general torque range of the Mitsubishi Rayon Family of shafts if one compares the torque of the 53 Bassara G-Series with the 60g R’s of the other products. Three and four degree tip torques are outstanding in this weight range of shafts. In light weight shafts, higher torques are needed to create feeling in the hands of the golfer.

Bassara G EiGj

Mitsubishi Bassara UltraLite Falcon

Bassara Falcon The lightweight Bassara Falcon has been in the lineup for a long time. Formerly known simply as the Bassara UltraLite, its EI profile is similar to the Diamana Blue Board. It was a great feeling shaft for lower swing speed players that benefit from a light weight golf shaft. The elastic titanium fiber used in the tips of the Bassara W and G series created a new generation of lightweight designs. The Bassara Falcon was discontinued in 2012. I am fitting the few I have left at a close out price. It is a great senior shaft. The are consistent from weight to weight and flex to flex. The torque ranges from 5.1 in the 43L to 4.1 in the 53S. The radial profiles are excellent; the shaft can be used in any orientation. The profile will be brought back in 2013 in a stock club.

Bassara F EiGj

Mitsubishi Bassara UltraLite Hawk

Bassara Hawk
The lightweight Bassara Hawk was a Diamana White Board on a diet. I never cease to be amazed at the range of players that simply crush balls with this shaft. The raw shafts weigh between 46 – 55 grams. For a skilled swinger that does not have the strength to load a White Board, this is a great alternative. Like all Mitsubishi Rayon golf shafts, the profiles of the Basara Hawk are consistent from weight to weight and flex to flex. The torque ranges from 5.1 in the 43L to4.1 in the 53S. The profiles are consistent from weight to weight and flex to flex. The radial profiles are excellent; the shaft can be used in any orientation. Discontinued in 2012 a similar profile is found in the JavlnFX Y.
