Wilson Champion's Choice Tennis String

A hybrid setup allows you to combine the best qualities of two different materials. In this case, you get the plush, responsive feel and power of natural gut alongside the spin-friendly texture and durability of a co-polyester string.

For the best performance, most players install the natural gut in the mains to maximize feel and power, while placing the co-poly in the crosses to provide control and durability. However, you can reverse this if you prefer a firmer string bed with more spin potential.

The 1.30 mm natural gut provides a slightly softer, more comfortable feel, while the thinner 1.25 mm ALU Power Rough co-poly bites into the ball more effectively. This specific combination balances comfort with the aggressive spin potential needed for modern baseline play.

While the co-poly adds durability, natural gut is generally more fragile than full polyester setups. If you are a heavy string breaker, this hybrid will last longer than a full bed of natural gut, but it may not be as durable as a full set of thick, monofilament polyester.

Yes, natural gut is sensitive to moisture and humidity. It is best to avoid playing in the rain or storing your racquet in extremely damp conditions, as moisture can cause the gut to fray or lose its tension quickly.
