I demoed this racquet a couple weeks ago and really liked it so I think this is the one I'm going to get. I'm looking forward to getting it, but now I'm kind of worried about arm problems now, flex rating is 72. The racquets I've been using have been more flexible, around 63, 64. Haven't seen much on this racquet so hoping maybe some of you guys have tried it out and have opinions on it. Thanks in advance.
