Gamma Synthetic Gut 16 Wearguard tennis string is an all-around performance string that offers longer life and enhanced playability for all playing levels and playing styles. The super resilient Dynalon Center Core delivers increased power and WearGuard Wear Resistant Fibers provide a longer string life with a crisp feel.
Plays well, good durability. I break strings every 15-20 times playing (doubles), and the wearguard seems to give a bit of extra life.
