The Signum Pro Thunderstorm is a axially twisted, decagonal string that offers excellent spin and control. This durable string has minimal tension loss while offering a comfortable, control oriented feel. This thinner gauge also offers a great playability.
The Black Edge Whirl is the twisted version of the Black Edge, in order to get you more control and spin. It is a comfortable co-polyester with massive spin potential and surgical targeting on full swings. With its twisted five sided profile, the Black Edge Whirl puts a tight grip on the ball, making it easier for the strings to grab and load the ball with spin. Designed with softening agents like polyethylene additives, this string is able to provide much more comfort and power than a standard polyester.
