I have a 27.25 (actually about 27.3) inch racket which I really like. Maybe it's me, but I sometimes "feel" that extra little bit of length and I'm not sure if I'd like the racket a bit more without the extra length. Two questions: 1) Is this a viable thing to do (cutting off 1/4-1/3 inch at bottom of racket)? 2) how much lead would I have to add to the butt of the frame to keep the same balance? Thanks. Racket I have is about 11 oz. strung.
