I have just re-picked up tennis after a break of 12 years since university. Back in the old days, I was a ground stroke player with heavy dipping top-spin off both forehand and double backhand, and with long back swing. My first serve was a flat serve and second serve was a high kicking serve. My volley was terrible and I tend to stay at the baseline. I was playing Price Graphite Oversize and have seven of these rackets strung with Price Top Spin 15L at 70lb. I am a synthetic guy and don"t like gut at all. Anyway, after two weeks of playing, I am beginning to pick up my forehand and backhand, but as I am now 38 years old, I am much weaker than I was, and find the Price Graphite Oversize too heavy. I also intend to work hard on improving my volleying, and my wrist simply cannot withstand the heavy Price Graphite Oversize. I notice a lot of new technologies on rackets and have seen people playing with O3 Speedport White, Babolat Aeropro, Pure Drive, etc. with "poly" strings (what are they?). Are they more like gut or synthetic? I need some help to choose a new racket because there is no shops in Hong Kong I know of which provide demo rackets, although the shops I visited recommended a variety of rackets. With my playing style (heavy top-spin forehand and backhand), can someone recommend me a racket and strings, on which I can also improve my volleying, while being friendly to the elbow and wrist? Many thanks.
