Ive hit with the Babolat aero pro drive cortex since the end of last summer. and ive improved alot since then. I am an aggresive baseliner so sometimes i over hit on shots usually down the line shots that i use too much arm on. On a scale for topspin from 1-10 i hit about a level 7 level topspin all the time. so i was hitting the other day and all my racket strings broke and had to run in the pro shop and use a demo. someone checked out the APD cortex so i tried the Pure storm. and i played a pro set and won. two days later i return to hitting with the APR cortex and i played this really good guy who was like a 5.0-5.5 and i lost the set 5-7. we had really good points and the reason i kept loosing points was because i was over hitting. what differences (good & bad) does the Pure storm have from the APD? what is similar about them? if anyone has hit with them and, if you don't mind leave your comments.
