I got fit about 4 months ago with a Trackman system. It put me in a Titleist 8.5 910 D3 with a stiff Bassara 50. Although I hit the new driver 10 yard further than my old FT-3 Tour 9.5 with Alidia NVS Stiff 65, I have 4 or more really bad drives a round. Is their any other shaft I should try or start the fitting process over?
