I currently use a 915 D2 8.5" driver with Diamana S+ 70 gram 45" shaft, and am thinking about a 917 with the same exact set up derived from a fitting. But before I do I wanted to experiment with a shorter 44" shaft to see how it affects my dispersion and a too often tendency to push the ball to the right. (I use the A3 setting to help with this).
Two Questions: (Aside from getting a whole new fitting)
I have a 13* fairway wood that has the same shaft only it is a 44" length. Would this shaft be essentially the same as if I cut the 45" driver shaft down to 44' properly?
Additionally, if I just cut 1" off the butt end for the purpose of my experiment would this affect the shaft flex/bend point too much to invalidate my results?
Thank you,
