Klipper USA Synthetic Gut 380' Reel 18 Gauge. Klipper USA. Power-Burst Racquet String - Klipper USA. Tennis Racket String. Does not move so strings stay straight and last longer. As an alternative to stringing the entire racquet with Power-Burst, reduce the stiffness of the string bed without sacrificing power by hybriding the mains with Power-Burst and the crosses with 17 gauge Zyex, Titanium Elite or Syn.
