Kirschbaum Pro Line II Rough 1.30 is a textured co-polyester tennis string designed for players seeking control, spin potential, and durability. Its rough surface helps increase ball bite for topspin and slice, while the polyester construction provides a predictable response during aggressive swings. The thicker 1.30 mm gauge emphasizes durability and a firmer string bed, making it a practical choice for frequent string breakers who prefer controlled performance.
Intermediate to advanced players with medium-to-fast swing speeds who prioritize control, spin, and string durability. Particularly suited to aggressive baseliners who generate their own power and prefer a thicker polyester string.
