Wilson Poly Pro is a firm polyester-based string with a very controlled, low powered response. It is perfect for intermediate and advanced players with long, fast strokes. From the baseline, this string rewards powerful players with heavy, spin loaded balls that jump off the court. This is a great tool for the modern topspin game.
