Head delivers a slightly softer version of the original Hawk. 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. This is a great option for strong intermediate and advanced level players who are looking for a very precise and accurate response when the stroke speed goes up.
