Driver Shafts

Access to a launch monitor will help. If your head speed is an average 88-92 mph, then you may well be maxing your carry. If the Bassara is launching too steeply and descending too steeply - minimal roll, then a different shaft may help. The 915 driver shafts are interchangeable with your 913, so one of the new stock shafts are one option to getting fit for a complete new driver. Most of these shafts at least have a R and S flex, so a good fitter can tune the equipment to you for max performance. Both distance and dispersion. Just with the no upcharge shaft options available from Titleist that it is impossible to guess the right shaft but probable that there a combination that will be ideal for you.
