Dunlop Black Widow 16 is a spin-focused co-polyester tennis string designed for aggressive players who want precise control and heavy ball rotation. Its seven-sided profile helps grip the ball for increased topspin and slice, while its relatively flexible construction provides a more forgiving feel than many firm polyester strings. The 1.31 mm diameter adds durability for players who hit hard and frequently.
Intermediate to advanced players with fast, full swings who generate their own power and rely on spin to control aggressive shots. Particularly suited for baseliners seeking a shaped polyester string with a balance of spin, control, and comfort.
