Poly Tour Strike is a poly-based monofilament designed for players with long, fast strokes. Compared to the grey color of Poly Tour Strike, this string has a tad less power, but it isn't as dead as a traditional polyester string. The high level of control will enable aggressive players to maximize stroke speed, resulting in easier access to pace and spin. Comfort is slightly above average for a control string. Durability is impressive, making this a good option for string breakers.
