Head Sonic Pro Edge 17L 1.25 Tennis String - 12 m  (Yellow)

Head Sonic Pro Edgefits perfectly inside the new generation of softer, more playable co-polys. As with the original Sonic Pro, we discovered above average comfort and playability. This doesn't mean it's going to be soft enough for multifilament or natural gut fans, but it does suggest that Head has created a very accessible control string. For our team the most impressive feature was the bite. With its five sharp edges, this string grips the ball very effectively and provides easy access to spin.
