Tornado will wreak havoc on your opponent with its exceptional spin potential. It offers a heptagonal shape that's axially twisted to provide maximum bite on the ball, helping produce more spin. This helps keep the ball inside the baseline while offering excellent longevity with the optimized molecular structure. Good ball pocketing and pop combine for controlled power.

Signum recommends stringing with 10% less tension than usual polyester or nylon strings because of the minimal tension loss.
