Shoulder Pain playing tennis

This is almost always the result of playing with monofilament strings (Polyester) over a long time.

If you need a durable string combined with extra control try one of the following

Tecnifibre Ruff Code (new Autumn 2011)

Tecnifibre Duramix

Tecnifibre X-Code

Luxilon M2

Wilson NXT Control

There will almost certainly be other strings introduced, which means this list could soon become out-of-date.
