It's all in the name. Wilson Champions Choice is a hybrid of two of the most popular strings: Wilson Natural Gut and Luxilon ALU Power Rough. Combining the ultimate playability of a high quality natural gut with durability, spin and control of a textured polyester gives the player the best of both worlds. For durability and control, use the Luxilon ALU Power Rough in the mains. For a softer feel and playability, use the Wilson Natural Gut in the mains.
