Really nice co-poly. Low power, firm, good...really good spin potential. Holds it's playability longer than most polys, and for as firm as it is, it does not bother my arm at all. I can't seem to find another string that has all the characteristics I seek at a better price... I'm sold on this one, I actually like it better than RPM Blast
Keeps its tension like no other ... firm but not harsh, excellent spin potential, no string movement. All this at a great price. Why pay more?
