Kirschbaum Set Pro Line II Tennis String

I used these in a hybrid setup (Wilson NXT Tour mains, Kirschbaum in the crosses) in a Wilson Pro Staff 6.1 BLX 95. This combination gave good feel and decent power with incredible spin, especially for my racquet. It's also very very soft on the arm for a poly. I don't tend to break strings, so I'm not certain yet the longevity. Highly recommended.

These strings lasted about 2 months for me. They are flexible compared to Wilson strings. I like them but will most likely try something else.

I strung these on the crosses along with Kevlar's on the mains. They are stiff strings, but feel beefy for 18 gauge strings. They play really nice - lots of power and really don't move much.Very nice strings - I am going to stick with these for a while.

I love these strings. 4.0 player. They last long enough, give me both control and spin, are easy on the arm, and they look good and stay in place. I've tried MANY strings over time, and these are the best for my game.

Perfect combination of power and spin. I came to zero on this after trying Wilson, RPM blast and Luxilon strings.This review is by a 3.5 player.

Good feel and tension stability for a poly. Reasonably soft for this type of string. I like it.

This German made string plays better than the luxilon and babolat strings that cost twice as much. I like recommending this brand to others who I string for and no bad reviews to date. Fast shipping and great customer service.

I love these strings, but when I bought I thought I was getting the standard ones. I opened the box and 4 of the 5 sets are the rough version, which I did not order. There's not a huge difference so I may keep them. Just be aware that the description on the website is misleading.
