This is the textured version of ALU Power. It has been designed with a rough surface to help the strings grab the ball (think spin). Like the standard version, this string has impressive feel for a firm co-polymer monofilament. It has been used in a hybrid by some of the greatest tennis players of all time. The low-powered response will enable you to take a full cut at the ball without losing control. As a result, you can generate massive stroke speed, which produces huge spin and impressive power. A great option for intermediate and advanced players who want durability, spin and precision.
