Yonex Poly Tour Strike is a poly-based monofilament designed for players with long, fast strokes. This grey version is a tad more powerful than the black version, but it still manages to offer exceptional control on full swings. As a result, you'll find it easy to maximize stroke speed for extra pace and spin. Durability is impressive, making this a good option for string breakers.
