Hello! I'm a tennis coach and i have a fresh contract with Babolat. I am currently playing with the AeroPro drive 2013 and it feels great at impact but i find it a little too head heavy for me. I have added about 10 grams in the handle but the balance doesn't seem to alter. i added some more and now it's better but it has reached 346 grams. And don't get me wrong the power and spin is tremendous in forehand but i have a little problem in one handed backhand returns. Anyway would you recommend to change to a pure drive or pure storm or just strengthen my hand?hahahaha.... Thank you!
