I think I would be happiest with a grip size of 4 9/16". I believe Edberg and Courier also preferred something like this. I see the average grip size between 4 1/8 and 4 5/8 is 4 3/8, but most players I know play with 4 1/2, and this will only be moreso in the coming years of bigger players. Do you think that manufacturers should start marketing a 4 9/16"? I see Wilson meeting this shift toward larger grip sizes again by having the new ncode 6.1 available in 4 3/4" (and the HPS 6.1), but it would help even a little more by having a 4 9/16". There is just something about it where all the bevels fit perfectly within my clenched hand.
