I cannot quite figure out why but this racquet, despite its stiffness rating, is quite possibly the most comfortable and crisp racquet I have ever had the pleasure to hit with. Weight, balance, power, control, everything about it is spot on. After the first step on court with the PDRGT+ I cursed myself silly for chancing injury. I had just demoed the RDiS200 and Ti-80 hoping to ease a shoulder injury I incurred last month and left the court with pain in both my wrist and shoulder. So there I am the next day, yielding a racquet 11 points higher in stiffness than either Yonex and after the first swing of the racquet I wanted to squeal…with delight. Been playing some amazing tennis—averaging 2 aces a game! Get this, I picked up a used PDRGT+ off the boards that was strung with Babolat Revenge at about 55 or so! The stiffest poly ever at 302! No pain! I don't get it! The last time I dared myself to string a full bed of poly I used Luxilon Ace at 51 in a TGK238.4 and after an hour I felt like someone was trying to reel a fish through my arm—ouch! I have clocked 5 hours of game time into this racquet over the weekend and my body and mind feel wonderful. I even forgot to stretch before and after my game today. What gives? I <3 Roddick!
