A Question, When teeing up what is the best position to put the golf ball (PRO V1 & PRO V1X)on the tee? Rotation arrow going straight down the middle or rotation arrow going left & right? I use a vertical swing and normally hit the ball relatively straight, swing speed is in the 75 - 85 mile an hour range - oh, and I am an old timer, 72. And yes I have tried all sorts of other balls, Wlson, Slzngr, TM, Prcpt, Swoosh and most likely other brands,Clubs are custom (by a fitter), Driver Swoosh (covert set at 10.5) Reason is due to dimple pattern on the ball. The rotation arrow starts and ends with a small dimple, with large dimples in between. Just asking --- need all the help I can get.
