The Kirschbaum Pro Line II 17 Tennis String Set is one of the softest and most durable polyester strings!
The Kirschbaum Pro Line II provides players with significantly more ball pocketing and forgiveness than most co-polymer strings. This string has a great durability and it maintains tension significantly well. It also offers the player a great blend of power and control.

Good for overall play. Even at 54lbs for me was too tight not enough pop. Switching to different string. Great product for players full swing with follow through.
