Ive been trying different strings over the past year, in search of the perfect combination of control, spin and comfort. I believe my search is over. I hit with a lot of spin, so Ive typically used rough string. Unfortunately, the rough poly that I primarily used in the past, Gamma Zo Tour Rough 16, is no longer being made. The Zo Tour string was always hard on my arm, strung at 54 main and 56 cross. Strung at the same tension, the Tour Bite Diamond Rough 16 has every bit of the bite on the ball, while at the same time being the most comfortable string Ive ever played with, while providing great control. Im very satisfied with the Tour Bite Diamond Rough 16, and Ill be using it from now on with my Head Youtek Extreme Pro 2.0 racquet.
