Kirschbaum Pro Line II Rough 1.30 is a co-polyester tennis string designed for players who want controlled power, spin potential, and a responsive feel. Its textured surface provides additional ball bite for topspin and slice, while the Pro Line II construction offers a more forgiving response than many stiff competition polyesters. The thicker 1.30 mm diameter adds durability for players who hit frequently and aggressively.
Intermediate to advanced players who generate their own power and want a controlled polyester string with additional spin potential. Particularly suited for aggressive baseliners seeking a textured string with a balance of control, feel, and durability.
