Head Hawk Rough - String Reel Colour:Anthracite Pro Penn Marathon is Penn’sHead adds a texture to their popular Hawk string and the result is a string that offers a firm feel and lots of spin potential. Because of its firmness, the power level of this string is fairly low, so it is best suited to players that possess long, fast swings. The string's rough texture means there is plenty of grip on the ball at contact which should act to enhance spin. Gauges: 17 (125) Material Construction: Co polyester Colours: Anthracite
