Kirschbaum Pro Line No. II offers tournament players an extraordinary mixture of power, control and spin-potential. A constant dynamic response of the stringbed and the maintenance of the installed string tension grant steady playing characteristics and performance. Works great as a hybrid! A more playable, slightly softer option to Kirschbaum Pro Line No. I.
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.
