I am a 4.0 player and I am about to purchase a new stick. Currently, I've been played with Babolat Aeropro Drive Cortex. I tried to put lead tape on them and all that. I am kinda sick of this sticks. Long time ago, I had a chance to hit the ball with Pure Storm and it felt perfect to me for some reason. Now I dont know what to get between Babolat Aero Storm Tour vs. Pure Storm Tour. I gotta try to demo Aero Storm Tour but I would like to hear your suggestion first. Please you folks advise me how these sticks are different. thanks.
