Tornado 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.
With this mould a straight shape is produced in the first production step. After cooling down the string is heated again and then axially twisted in a second production step. The twist- and double heating process makes this string very comfortable, the rough surface provides an exceptional spin, but the feeling is not as stiff as usual shaped strings.
