Wilson Champion's Choice Duo Tennis String

A hybrid setup allows you to combine the best qualities of two different materials. By pairing natural gut with polyester, you get the arm-friendly comfort and touch of the gut alongside the spin potential and durability of the polyester.

For the intended performance, place the natural gut in the mains (the vertical strings) to maximize comfort and feel, and the polyester in the crosses (the horizontal strings) to enhance spin and durability.

Yes, the inclusion of natural gut makes this setup significantly softer and more forgiving on the arm than a full bed of polyester strings. However, if you have severe arm issues, you may still want to consult with a professional stringer about your specific tension requirements.

Natural gut is known for holding tension exceptionally well, but polyester tends to lose tension faster. Because this is a hybrid, you will experience a more gradual drop in performance compared to a full polyester setup, though you should still expect the polyester component to eventually go dead.

Yes, the polyester component is specifically included to help the strings snap back upon impact, which generates the friction needed for heavy topspin. While it may not offer quite as much bite as a full bed of textured polyester, it provides a balanced blend of spin and control.
