Signum Pro Tornado Set

The Signum Pro Tornado is a monofilament string. This means it has a strong polyester core. The advantages of this are tension retention and durability. The 7-sided shape of the string makes it possible to add a lot of spin to the ball. The co-polyester composition increases the string's elasticity and therefore provides more comfort and power than other strings. The string is available in different gauges. When a string is thinner you get more feel and control and the string is more elastic. But when the string is thicker, it is stronger and more durable.
