“The first thing I was told when I strung with Pro Line II was “How can you play with a red string?” But soon after I told everyone to try it and they all went very enthusiastic so now red is cool. Furthermore, even if the string is a co-polymer its the most playable one, without loosing tension, has control and durability.

Player Comment

“I’m absolutely dumfounded with Pro Line II. I had my Head Microgel Radical racquet strung with this string, purely because of all the positive comments about them. Everyone is absolutely correct. These are world’s better strings, well above Pro Hurricane Tour, Big Banger Rough and K Gut Pro combined!!!! They feel soft and firm at the same time, with huge spin potential. The thing that frustrated me with Pro Hurricane Tour and Big Banger Rough is when you string the entire frame, you had control and spin but the frame felt dead and killed my game. Try it out for yourself and don’t bother with any hybrid more in my opinion. The feeling is amazing with it in the whole string bed. This was my first try with Kirschbaum Strings and I’m so glad I did!!!”

Meet the designer: Horst Kirschbaum

The family line of Pro Line II is third generation polyester. It comes from a development of new materials and mastering the low temperature fusion at witch they are processed. The result is a string that feels similar to a synthetic gut regarding playability but with all the virtues of Poly’s. This is a special string that does not move and hold tension longer.
