The Wilson sting has always been one of my favourite racquets but I've never had the opportunity to hit with both the PWS and non-PWS versions. Just wondering if anyone has hit with both and can offer up a comparison, assuming there's some difference. Also, I do recall there being a Wilson Sting (midsize) that had red piping instead of the typical blue stripe. Any difference there or just a cosmetic variation? Oh, just wondering if anyone can provide the specs for the Sting Oversize. TW had the specs listed, for the mid, as being: Head Size: 90 sq. in Length: 27 inches Strung Weight: 12.6oz / 357g Balance: 7pts Head Light Swingweight: 326 Stiffness: 61 String Pattern: 16 Mains / 18 Crosses Does anyone know what they'd be for the OS ?
