I have a 910 d2 driver 9.5 loft at c3 so its at 8.75 hit the ball at a nice trajectory but get max 3 feet of roll. my ball carries 240 - 250 on a good hit. i play the pro v1x and a penta. Anybody know an answer . I live in the northeast so its always a little wet but even on sunny days i dont get roll?
