for all those owners of a wilson prostaff, whether it be an original or ncode, is it true that the sweetspot is actually lower then the center of the string bed? i don't quite understand if this is good or bad. on my backhand, i always tend to hit the ball on the upper portion of my strings but then get now power. so i try to hit closer to my shock absorber, which is on the other end, and now i get some sweetspot and a better feeling shot. i'm just asking this because thats what it says under the wilson technology page. does anyone else feel like this messes up their game?
