Hi I am a junior golfer with a driver swing speed of 85-90 mph. In tournaments and matches, I like to play ProV1's because of the great distance and feel. I was wondering if I'm getting the best performance out of my ball with my swing speed being low. Does my speed matter? Can I still use my ProV1s or should I look at a different ball like the NXT Tour or Velocity?? Any suggestions would be appreciated.
