Re: What tennis racquet do u use?
Since the Yonex Vcore Xi 100 has just been released, it would be hard to comment on its performance. According to their specs, both of them are quite similar except for a few minor details (Xi is a bit stiffer and has a synthetic grip). But it all depends on you actually, if you are a risk-taker go with it, but if you prefer to be conservative go with Yonex Vcore 100S.
