Wilson Champion's Choice Duo Tennis String

The Wilson Champion’s Choice Duo is arguably the most famous hybrid string setup in tennis history, famously used by Roger Federer. It combines the two peak performers of the string world: Natural Gut for unmatched feel and Luxilon ALU Power Rough for control and spin.

This is a pre-packaged hybrid set containing two half-sets of string. By combining these materials, Wilson aims to eliminate the drawbacks of using either string alone (gut can be too powerful/uncontrollable; poly can be too stiff/dead).

• The Gut: Wilson Natural Gut 16 (1.30mm) provides the ultimate in elasticity and tension maintenance.
• The Poly: Luxilon ALU Power Rough 16L (1.25mm) is a textured co-polyester that adds "bite" for spin and stiffens the string bed for control.

Performance Profile

1. Feel (10/10): The highest possible rating. The inclusion of natural gut provides a "connected" and "plush" sensation that no purely synthetic string can match.
2. Power (9/10): High energy return, especially if the gut is placed in the mains. It provides "easy depth" on defensive shots and extra pop on serves.
3. Spin (8/10): The "Rough" texture of the Luxilon component helps grip the ball, while the snap-back of the gut adds to the ball's rotation.
4. Comfort (9/10): Far more arm-friendly than a full bed of polyester. It absorbs heavy impact vibrations, making it suitable for competitive players who want to avoid injury.
5. Tension Maintenance (9/10): Because natural gut does not "go dead" like synthetic materials, the playability of this hybrid lasts significantly longer than a full bed of poly.

Best Suited For

• Intermediate to Advanced Players: Those who have the swing speed to utilize a poly but want the premium feel of a pro-level setup.
• Roger Federer Fans: Specifically designed to replicate the exact feel used by the Swiss Maestro.
• Competitive Players with Arm Sensitivity: If you need the control of Luxilon but a full bed of it hurts your elbow, this is the premier solution.

Note:

Because it contains natural gut, this string is sensitive to moisture and extreme humidity. It is best to keep your racquet in a thermally lined bag and avoid playing in damp conditions.
