The SL series uses the 'Muscle Tec' string system, to enlarge the power zone of the racket by allowing the strings to move over a smooth rounded surface rather than being static as in conventional rackets. 'Muscle Tec' enables rackets to be strung at a lower tension yet still gives a high tension feel. It also uses Nano Technology and Nano Superlight Resin.
