| Solinco Tour Bite is a firm and durable co-polyester that delivers an almost unbelievable combination of spin and precision to players with long, fast strokes. This explains its growing popularity at the collegiate level where control at high head speeds is a must. Our testers noticed immediately how well the square profile gripped the ball. The low power level allows big hitters to load up on head speed and attack the ball at an extreme angle. In the right hands this string produces a very heavy ball.
