TG PRO - Tennis String Co-polyester tennis strings are the modern standard for intermediate to advanced players. They blend polyester with other additives to provide exceptional spin, control, and durability. While stiffer and lower-powered than multifilament strings, co-polys reward aggressive, long, and fast swings with heavy topspin and precision. Who's it for? Intermediate to advanced players who want a spin-friendly hybrid string that bites the ball without sacrificing feel. Key Features: Spin Production: Co-polys, especially shaped ones (like pentagonal or octagonal profiles), grip the ball and allow for massive topspin generation via snapback. Control: The stiffer string bed prevents the ball from launching, giving players the confidence to swing freely without hitting long. Durability: Excellent at resisting string breakage, making them ideal for frequent string-breakers.
