OR PROBABLY NOT PLAY WITH WILSON RACKETS at least in my opinion they change their ranges too often. I thought the 7.1 zone was nice, but it did not last long and did not have a suitable replacement. The H series did not last long at all before the ncodes. Babolat has never changed the Pure Drive in the US and it is selling strong. Wilson's competitor, the surge, is now on its 3rd version. I hate the thought of buying a racket that will be discontinued in 2 years especially considering it takes a few months to totally adjust to a new racket. Don't get me wrong, WILSON MAKES GREAT RACKETS--great rackets that are discontinued much too quickly. The ncode 6.1 95 is sweer, but who knows how long it will be around.
