Named Black Code Fire, this comfortably firm co-poly string is made for big hitters who want the control of a polyester but with lower impact vibrations and less shock on off-centre impact
Black Code gets its great feel in part from Thermocore Technology, which is a manufacturing process that uses heating and cooling phases to soften the string
This string also has massive spin potential thanks in part to its 5 sided profile
Intermediate and advanced players looking to attack the ball with powerful strokes (without having to worry about overhitting), should love this string
The fact that it puts less stress on your arm than the average poly is a very nice bonus!
