When you put this Head Hawk Touch 1.25 12m Set on your racquet, you better already have things under full control. This co-poly has Head's unique Crystal Core technology, featuring a pliable inner core surrounded by a firm outer shell. The result is a string that is firm enough to deliver exceptional control but also muted enough to reduce the harshest vibrations. The low-powered response will allow big hitters to take huge cuts at the ball, a fact that bodes well for those who want to ratchet up the spin. Designed for high-level Tour and tournament players, the string's elasticity allows for accurate feedback and exquisite feel so you can follow through with your versatile game and perfectly control every stroke and, ultimately, the game.
