Kirschbaum Pro Line II 1.30 is a co-polyester tennis string designed for players seeking dependable control, durability, and a consistent feel. Its smooth, round monofilament construction provides predictable ball response, while its relatively comfortable characteristics make it a more forgiving option than firmer polyester strings. The thicker 1.30 mm gauge emphasizes durability and a solid feel, making it a practical choice for players who frequently break strings or prefer a more substantial string bed.
Intermediate to advanced players with medium-to-fast swing speeds who want controlled performance and increased durability. Particularly suitable for aggressive baseliners and frequent string breakers who prioritize consistency over the additional feel and spin potential of thinner gauges.
