Pretty much exactly what Matt said

I' ve found them to have a bit more creep intially, but have not had any center or end serving problems (on 3 different bows)

And also as Matt said, they are noticeably quieter than a WC. WC strings have a noticeabl " PLOCK" sound that kind of erks me. I put a a WC string on my CyberTec and it definitely picked up that " plock" sound. Of course, otherwise, it wa a far superior string to the HOyt factory stuff.

Six of one, half a dozen of the other.

If given a choice, I' d take WCCB but so far I haven' t felt the need to change out the Stone Mountain strings. They are the best " Stock" bowstrings I' ve encountered yet.
