Tornado is a heptagonal-shaped co-polyester string offering a high level of dynamic power while providing exceptional access to spin. This string is axially twisted and dramatically increases the spin potential compared to traditional round strings. Signum Pro Tornado also offers excellent playability and comfort for a co-polyester string. This next-generation string provides a new optimized molecular structure, which, as a result, makes the Tornado hold tension remarkably well. The Tornado offers excellent ball control and is among the most durable poly-based strings we have playtested. The unique anthracite (black) color looks great on nearly every racquet. Tornado is part of the new Blackline® power series from Signum Pro.
