Polyester. Genesis’ Black Magic string gives you the best balance between power and control. This comfortable string gives you an enhanced feel thanks to a softer monofilament co-poly construction. While most polyesters on the market today are hard and rough to the feel, Black Magic offers a soft feel while still delivering excellent tension maintenance and durability.

  • Q:

    I use synthetic guts strings with 60 lbs. tension, do I have to lower the tension with this poly string?

      While there is no specific requirement that you lower tension when using a polyester string, I usually recommend dropping the tension by approximately 5% (usually 2-3 pounds). Polyester strings are stiff, so reducing the tension helps offset that stiffness for slightly more comfort.

Genesis puts all of their string through rigorous testing to bring tennis players of all levels the very best.
