This string is great. Coming from a full poly setup, I put the ZX in the crosses, and it gave me much more power and feel. For players looking for a string that plays like a polyester, but is easy on the arm ( this string has a stiffness not much higher than natural gut), this is the string for you. This string is a little tricky to string, but when installed correctly, it is immaculate. The strings move a little more than polyester strings, but that isn't a big deal for me.
