    Which shaft of the B. Asha series would you say most resembles the Matrix Black Tie in regards to flex ( tip to butt ), spin, dispersion, and feel?

    Fascinating test. Alas! it appears that efforts to define and utilize one’s swing DNA are simply exercises in futilty. With the exception of backspin, there apear to be no significant differences in outcome regardless of which shaft was used. Furthermore, the shaft’s profile does not seem to account for the reported differences in back spin. I believe that Mr. Wishon has opined that with the exception of late release golfers(eg Sergio Garcia) the shaft will have minimal impact on the results of a swing. Accordingly, fitting, fitting, fitting involving a plethora of shafts remains the only way to find the “perfect shaft”.

    Any thoughts on why the 5S spun quite a bit less then the 5X and 7S?

      Not really. I didn’t notice anything when testing (I try not to pay too much attention to the numbers when swinging). It’s not the only time a shaft that “should be” higher spinning hasn’t turned out that way. I think it just speaks to the importance of fitting.

    Kudos to Miyazaki for the international code system, I wish the industry would adopt this system across the board, it would take some of the mystery away regarding shaft matching. It would be good to see the archaic flex labelling be replaced by what is a far superior system.

    I’m just curious why some one would put a $249.00 shaft on a 299/399 Driver. Does that shaft add that much distance?
