I've played every weekend in the spring summer autumn for about 6 years. Good athlete, Good service motion, hit the ball consistently hard and deep, but I've always used crap rackets and it's about time i do justice to my game.
well, the mahogany drive is a very easy racket to use. i would recommend something a bit harder to help you improve further. here are some to check out:
wilson npro open
babolat pure storm (again a bit wood like)
yonex rds 002
dunlop aerogel 300
fischer m pro number 1 light
volkl dnx 10 midplus
head microgel radical
all those rackets are 98 sq inch heads and about the same weight as the mahogany drive. the ones at the top are stiffer and the bottom ones are more flexible.
