We refer to it as HAWK when control and explosive power are perfectly balanced in a string. Thanks to the novel Crystal Core Technology, a special manufacturing method, the outer molecular chains, which affect power, and the inner crystalline core, which affects control, are precisely balanced in this monofilament string. These strings are the ideal tool for the elite Tour and tournament player because they are quite strong and have a lot of spin potential. Ultimately, immense power entails great responsibility.
