Around the first of July, I ask which ball was best of the tee with a 88 mph swing speed and I appreciate the reponses from all. I went back to a pro and got refitted with a new driver. Increased my speed to an average of 95 mph and about 40 more yards of distance and carry. Didn't have to change brand of balls either!!! Happy Camper Now!!! Thanks again to everyone and their suggestions.
