Over the past year, I've seen a significant drop in my speed-from 18.3 mph to 15.5. Strangley, my rev rate has stayed the same. I've tried holding the ball higher, higher backswing and even moving further back on the approach and it's not getting me back to where I was...
so, whoever has made the change-how has it worked out so far? Most importantly, have you seen any changes in hitting power/deflection?
