Testers

We do our shaft testing with humans not robots. But we use humans that have robot like swings, ­čÖé They have the┬árepeatably in their swings to give us numbers we can use in comparisons of how a shaft influences launch, spin, dispersion and distance. ┬áBut, most important, they can tell us the most important thing about a shaft that a robot cannot, how it FEELS.

    plz tell me the cpm frequency of diamana blue shaft

    • DevotedGolfer

      If I posted a number it would have very little meaning. CPM is subject to many factors, clamp position on the shaft, length from the clamp, amount of weight, and clamp pressure. You have not said which Diamana Blue, there are many now that the third generation is available. If you want to compare stiffness, look at the stiffness numbers of different shafts I put in the charts. It is in pounds of a 4″ deflection after a 1″ deflection preload. It is much easier to quantify and understand than frequency.

        Whew, glad I started reading your blog, like 10 years ago…lol

    Have you tested the new Veylix shafts?

    • DevotedGolfer

      They are in the shop, the weather here in DFW is keeping me indoors so you will see the numbers soon and the hitting tests shortly after

    I’m looking at the shaft profiles of the Matrix Reign HDZ and Project X HRZDUS yellow shafts, and they look very similar. Am I correct in that assessment?

    • Interesting observation. I would say the HDZ is a bit more like the Project X Loading Zone than the HZRDUS Yellow. The difference is in the butt sections, The butts of the Reign are much more conventional, going stiffer consistent up the shaft from the soft mid.

    If you use a 1″ shaft extender in a driver shaft that was butt cut only. will it significantly change the profile of the shaft?

    Since Srixon has entered the US market….with gusto I might add, and they are using great new Miyazaki shafts; how about a review of some of them. I’m playing em, and they are as good as ever!

  • Rick Talley

    Can you tell me some suggestions for some of the newer shafts that are similar to the Matrix MFS 60×4 white tie profile? Thanks!

    • The Paderson Kinetix IMRT KG860 model has same bend profile is is a degree higher in torque. The entire Paderson line is being measured. They sent in over 100 shafts and it is taking a lot of my time to get that many shafts measured. Also coming, a box full of new Aldias and a complete review of the AeroTech line.

        Thanks for the reply. Never have tried a Kinettix shaft. Right now I’m going through an ultralight phase. My 2 gamer shafts at present are a Miyazaki Kuala Mizu….ultra smooth, and my trusty point-and-shoot Matrix White Tie. Going to give a 50 gram PX LZ16 a go next week, and really intrigued with the Bassara GG or Phoenix. I knew it was a mistake to try my buddies Grand Bassara….very interesting shaft….but just hot butter feel. Hate his driver, though…..so time to experiment!

    I know you guys sold some shafts at great price points, and that you were planning to continue this practice. Are you proceeding with those plans? If so, any chance you’re going to offer any of the new Bassara models? Thanks!

    • Since this site went subscription I have offered special pricing on recently reviewed shafts privately to lifetime Devoted Golfer members. That will continue. The Bassara’s were reviewed before this practice was instituted. You are on the mailing list for these offers. Being a Devoted Golfer member, you can contact me privately for your shaft needs.
