I am really excited about this new racquet as my game is all about spin. I can't hit flat even when I want to. I am seriously thinking about getting this racquet (perhaps even before the club tourney on Thu!). However, I can't decide which model to get. I currently play 2012 PD, but until PD, I mostly played Prince OS racquets (NXG OS is still near and dear to my heart). The TW review seems to knock the 105S for stability, but I am guessing I can just use lead tape to make the racquet feel just like my old NXG. Or should I just go with 99S since that is the model that everyone seems to love? What do I DO????
