Is the weight of the racket or swing weight more of a factor when trying to pull the trigger when returning hard hit balls? Which is more manuverable? The Slazenger x1 weighs 12oz but only has a swing weight of 316. The AeroPro weighs only 11.3 oz but has a heavier swing weight of 324. Does the head size come into play as well? 95sq.in vs. 100sq.in? Thanks for any feedback.
