I am a recreational club tennis player and I am looking for tips that can help me to improve my game. Right now I am looking for a new racquet. I currently use a Head TI S4 and an S2, which are light titanium racquets. I used to use TI Rip Fibre string but Head retired that string so now I use Luxilon, which I love, 17 gauge. Not sure if I should get a slightly heavier and slighly smaller head raquet. I have good control, a reasonably strong topspin forehand and mostly a spin backhand, though I do like to use a two haned backhand. So, any tips on racquets you are using and recommend is welcomed. -- John
