Head Lynx String Reel is a medium firm co-poly that delivers remarkable precision on full swings. The string is ideal for players with long, fast strokes. With its lively snapback, Lynx should help topspin players hit a heavy spin loaded ball that explodes off the court. Built with additives to increase elasticity and feel, Lynx also performs well on slower strokes where it possesses above average touch for a firm monofilament. The Head Lynx is recommended for intermediate and advanced players.
