hi.. thanks for replying though this thread is quite old now. have gone back to using my AT 700 which i find is still the best. went through a phase where i kept changing rackets but now i'm sticking to only AT 700.
haha.. yes i have, haven't i? .. well not directly... in between i was using NS 7700 as well for a short while too. i guess i finally developed enough strength to use at700.
good for you. the most important thing is that you're comfortable using the racquet. all this nonsense about head weight, shaft stiffness and grip size doesn't really matter, if you like the feel of your racquet, then that's the one for you.
