Played tennis for 30yrs to a good club/team standard. Mainly doubles of the old-style serve and volley school. I've had some arm issues in the past, so, looking for new racquets I'm after something that's arm-friendly, weighs about 300-320g and is definitely head light when strung (I've tried a couple that are advertised as headlight, then when they turn up......... I have a new Volkl Organix 6 at the moment which is great. Strung and re-gripped it weighs 300g has great "pop", is easy to handle at the net but I think is head-heavy so on serves and overheads is causing me some pain. Anyone have any alternative suggestions?
