I come to all of you with head bowed in respect, since I know someone will help me get my mind wrapped around this. Ex. I hit fantastically with two racquets that have completely different specs. Rac. 1 is 11.4 oz, 4 pts HL, Rac. 2 is 12.8 oz. and 8 pts HL. They both are demos and both feel exactly the same in a match. Now, I have demoed racs. with slightly diff. specs either way and hated them. Both racs. I like above are 95 heiads. Is the answer perhaps directly proportional to the ratio of weight to the frame's balance?
