anyone know if there were any models besides the st vincents that had recommended tension ranges 55-65 lbs written on the throat with a sticker? I am just trying to ID a racquet I just bought. It may be early taiwan, but I was under the impression that Wilson changed the tension to 50-60 once the racquets moved away from St Vincent. Could this be a racquet that was started in St Vincent, and finished in Taiwan? Buttcap says JRQ or possibly JRO, can't tell... need a microscope.
