It depends on the feel you want. I have 2 Aero Storms. I got they at seperate times so naturally I added overgrips as I went along, trying to find my perfect fit. I found out 3 over grip over my 4 3/8 was the right size for me. So one the stick I got first I have 2 used overgrips with the third being replaced once used. On the newer stick, since I new the number of grips I liked I went ahead and put those on there, and I like how the new over grips make the whole grip even as compared to the other where the bottom in a bit smaller since that is where most of the wearandtear takes place.
