Gamma FTX 17 tennis string provides exceptional all around synthetic gut performance. Added cross-woven foil wrap for improved resiliency and improved durability. Provides faster string return on impact for more penetrating ground strokes and faster serves. Thinner 17 gauge for added playability.

This string gives me the right amount of feel, comfort, and power to play amazingly. I have never broken a string and I have been using this string since late May so it's also very durable and I played 5or 6 times a week for about 2 hours.
