Currently have a Carlton PU overgrip over my YY 3UG5, orig grip intact w/o the plastic. I find myself a bit slow when changing grips (forehand -> backhead) when defending against smashes. My right hand roughly measures 18.5cm (from bottom of palm to tip of middle finger). Would removing my original and getting a replacement grip (so that overall handle diameter is reduced) next time help? Incidentally, would removal of the original grip affect resale value? Or do I just need more practice, re: http://www.youtube.com/watch?v=hG0OQu6WHoE&feature=player_profilepage#t=46s? Any thoughts? Thanks.
