He has over 10 years experience building and fitting golf clubs.  Russ was an early user of fitting with a FlightScope 3D radar launch monitor. He worked closely with SwingView Pro and FlightScope during the integration of video into the radar ball and head tracking software.

Golf Digest 2013 Americas 100 Best transparent.fwRuss has been named one of America’s 100 Best Clubfitters by Golf Digest Magazine in 2011 and again in the 2013 update of the original list. At one time he was active in the PCS and the AGCP, club building and fitting organizations.  The AGCP named Russ a Master Fitter and acknowledged his contributions to the trade with the 2009 AGCP technology award.

Living in the Dallas Fort Worth metroplex, Russ has access to the UST Mamiya Headquarters. It was there that he was first exposed to the concept of EI deflection measurement of shaft bend profiles.  That exposure lead to design and development a precision instrument for measuring EI.  Shortly after, a process of measuring GJ was developed. He created and maintains the databases that are the source of the charts and tables you see here.  The authors of the reviews at GolfShaftReviews are owners of the EI instruments and contribute their measurements to the databases.

    Great site! I learn alot on shaft, especially with the EI profiles available…

  • Greg

    Thanks for all the hard work & info. It’s really amazing. Can you help me w/ my research… I’m trying to find a driver shaft that is tip stiff & can help keep the ball down. I currently using taylormade R1 TP w/ tip stiff shaft. The shaft is taylormade – I believe Mitsubishi makes the shaft for taylormade & offers the same shaft independently.

    Your website is great but I wish you were able to enter the desired shaft specifications & the website would search the current database providing a list of shafts meeting those specifications. Is there a way to research the entire website trying to find a number of choices? It’s very difficult to read through all the different shafts, trying to narrow down the list to just a handful of choices…..

    Thanks for your help.

    • Brandon

      I think many of us reading this info would like the same thing. Perhaps a web app or downloadable excel sheet that would meet these requirements?

      Thoughts on this Russ?

  • Brandon

    Perhaps I haven’t been as diligent in my reading of the EI profiles as I should have been…is there a page that explains the significance of the profile in terms of predicted launch and spin?

    Hello Russ:

    Great site with lots of information. As a professional club maker, I’d agree to the quality of shafts being made by today’s shaft manufacturers. When was the last time you reviewed a “bad” shaft with less than acceptable radial consistency? The last shaft I had a problem with was one from Veylix that possessed very pronounced spines when put through a spine-finder.


    • DevotedGolfer

      Marc, I have seen enough shafts that I can recognize the manufacturer by looking at the production label on the butt. Some factories do not ship anything but good shafts. Others appear to ship everything they make.
      I don’t know how you test for spines. I use a tip weight with a laser. I find a FLO, then note the cpm at that point, I then turn the shaft 90 degrees and find the other FLO and again note the cpm. If they are less than 2, the shaft is good. Otherwise, a shaft company gets a phone call. When the Graphite Design folks were in my shop, I was demonstrating this practice and was told that is exactly what they do in their factory. I have never seen a bad shaft from them. I have requested review samples from Veylix, but they never arrived. So I cannot comment on their uniformity or design.
      Ok, I danced around your question a bit there. From the bad factories, I see about 15% that should have been scrapped. From the good ones, 0. My understanding is that Veylix is made under strict quality standards, so I would not expect to see anything that would fail.

  • pamela

    Is there a steel shaft made for fairway woods…Ex. Callaway warbirds

    • DevotedGolfer

      Not that I know of. But if you get involved in the 80+ gram graphite shafts, you can find many that are stiffer than steel.

  • Rick Huntley

    Russ recently fitted me with JPX850 Mizzuno driver and 3 wood. Through his analysis he matched me to the perfect shaft for each club. I am now hitting each 20 yards further than my prior clubs-Russ is extremely knowledgeable and a true professional. Thanks Russ

  • HR

    I am interested in the Aldila RIP iron shafts. Have you analyzed these yet? and/or do you have any specific information about comparisons on them? Thank you.

    • DevotedGolfer

      Ah, so many shafts so little time. Nope, didn’t ever get to those. Perhaps latter this summer.

  • Richard

    Love the site, wish I had a better understanding of the science 🙂
    Would love your recommendations of a premium shaft for a callaway 815 driver, fed up of always being custom fitted for a standard shaft, never given an opportunity to hit a premium shaft.
    Would like to be able to request a try of a shaft when I go to callaway fitting centre.

    • DevotedGolfer

      You know it is impossible for me to recommend a shaft without testing. I do appreciate your frustration. The expense of putting premium shafts in a ftting system is placed on the fitter. The stock shafts are provided by the head company. So, most retail fittings are restricted to the fitting cart. The top fitters invest in the premium stuff to the extent they can justify it.

  • Nikhil Raj

    Hi Russ, Been a long time lurker and absolutely love the information you and testers publish! I’ve recently come across the shafts by Robin Arthur of Graffaloy fame and now of the Excalibur line of shafts. Any chance you can test these? I’ve been installing the Tour line for some mini-tour/amateur players and they absolutely love performance and would love to see these profiled.

    • DevotedGolfer

      I sent Robin another request for review samples.It is not my first request. I would like to review his products.

      • Nikhil Raj

        Thanks Russ. Hopefully he’ll come through this time around.

        • I have not heard from him, perhaps you should encourage him.

    Russ, can you help me with some shaft recommendations? i am a 1 hcp senior level player. I just purchased the Cobra King Ltd driver. The standard shaft is the Aldia Rogue Black 60g. I have a reg. with the loft set to 12 degrees. My driver speed is 92- 95mph and my smash factor is +145 on most days. My tempo is medium and my change in direction a little fast. I like the driver the ball tumbles and I get lots of roll. My spin rates appear to be low can you recommend any shafts that will give a little more spin. Thanks.


    • It is hard, no it is impossible to recommend a shaft that will add spin without seeing how your react to the shaft, how it balances your club, and how all that interacts with your swing dynamics. A regular Rogue Black with our swing speed should be delivering some spin, it is not a low spin design. However, that said, it has more to do with how you interact with the shaft than any particular property of a shaft.

  • Josh

    Do you have any info on how shafts change with use and/or age? I was fit into an AD DI 6x driver shaft and have playing it for about 5 years now. I was struggling with my driver control last season so I started testing new clubs and noticed an immediate difference. I don’t have an apples-to-apples comparison (old driver was a Cobra, and they’ve changed hosel adapters so many times that I can’t just put the fitting cart shaft into my old head), but a new AD DI 6x feels significantly stiffer than my old one.
    On a related note, do you have any data to show the effects of keeping a shaft in a hot car trunk through the summer? I love the convenience of having my clubs with me at all times, but it’s not worth ruining a thousand dollars worth of graphite.

    • Josh,
      To the best of my knowledge shafts do not deteriorate with age. I do not believe the temperature in your trunk will affect you shafts. But it will dry rot your grip and over a long period of time it is not good for golf balls. I recall the plastic medalions on the back of some iron heads were popping off in the Texas heat when left in a trunk.

    Russ, any comments on the ust elements chrome and chrome platinum. I am thinking about purchasing one or the other. Right now I have the matrix black tie 70m4 in x flex and have a tough time controlling the side spin (left to right). Also looking to pick up a little distance too (who isn’t). Thanks for your input

    • Sorry, UST has not been willing to provide review samples.

  • Jsmithx4

    Hello Mr. Ryden,
    Really enjoy your website. Are you still using the Fubuki J shaft in your driver?

    • I have taken to trying new shafts to write better reviews. That is not always a good thing for my scores. The Fubuki J remains one of my go to shafts when I am concerned about beating my buddies on the weekend.

  • billm311

    Russ, have you seen any low trajectory, low spin shafts with a high balance point? Like a Diamana whiteboard or Aldila Rogue, with the balance point of a Diamana S+ LE?

    Is the Diamana S+ LE really higher balance point than the standard S+?

  • Nocklaus

    Hi Russ.
    Since I am a tweaker and a shaft ho, I love your site.
    I am just wondering why you have to use Fubuki J50 in X stiff?
    I am 62 with a ss of around 103 mph. Smooth swing. I have a Fubuki Z50 R that I like. Carry around 230-240. Feels a little bit soft but the S is to stiff. How can you use an X ?

    • Weight and flex must be read together. On most shafts the 5X is just a bit softer than the 6S. And it weights a bit less. You have to know the matrix of weight / flex for a model to see the stiffness grid.

      • Nocklaus

        Sure, but you use 5X and I use 5R…?

        • Each of us reacts of stiffness and profile differently. That is why working with a professional fitter who has a range of profiles in a matrix of weights and stiffness is important. I am fortunate, I am a professional fitter with such a matrix of shafts and can tinker with shafts endlessly. I know from watching acceleration graphics on FlightScope what a good release feels like. And how much speed it adds to my swing. Which, with the onset of age related stiffness is about 3/4 of what it once was. As of two weeks ago, a limited release shafts, the KuroKage Limited, 50S went into my Driver. TiNi wrap the entire length of the shaft. It is not made in 5X so I had to settle with the 5S. It feels good, but when I really unload the ball goes a bit high. So, knowing that I may bring in the 6R and test it, it is the next in the matrix. I don’t really pay much attention the the letters on the shafts because I have all of my own data on them.

    Hi Russ

    Question for you. I was wondering if you could compare the project X lz versus the modus 130. I quite liked the 130 in my previous set but they were a tad spinny in the S flex. I
    Have been playing the lz 6.5 and they are nice just want a bit of a compare and contrast.

  • Paresh amin

    Russ any comments on true temper’s dynamic gold X7 shafts. Looking to replace my rifle 7.0 with them as to bring the launch and spin down. But I fear a “telephone pole” type feel. Thanks again for the great work

    • I have not looked at them yet. Your comment prompted me to request a review set. Thanks
