Tourna's Big Red string is a firm co-poly designed for players with long, fast strokes. It delivers a firm feel and great feedback, which lets the player know exactly where the ball is hitting the strings. Our playtesters were impressed with this string's control on full swings, even when installed at the low end of the tension range. With its thin 1.20mm gauge, Big Red puts a very tight grip on the ball, enabling the player to impart huge spin on the ball. This is a great option for big hitters looking for spin and control. Offers slightly more feel and spin than the 1.25mm gauge.
