I was walking out of the club the other night after hitting and slipped on ice in the parking lot and fell on my bag. My aeropro drive now has a super tiny crack in the hoop just above the throat. The crack doesn't even go the full way around the frame, but this seems like a good excuse to buy a new racket. My current choices are an aeropro drive with cortex, or a pure storm. Is there any noticeable difference between the cortex version and the non-cortex version I am currently using? And as for the pure storm, does anybody have any feedback on this racket? Hopefully I will be able to demo both, but any information I can get will be greatly appreciated. Thanks!
