Yeah what he said!I once bought a used bow with brand new WCs on it and was very disappointed with the X coat. It didn't take long for it to start looking shabby and it made the rest of the string look like a piece of junk. To be honest, I wasn't impressed with the string either and couldn't wait for a chance to get it off the bow and replace it with something else.
You need to lube the cable guard rod periodically. I just bought a delrin weather tamer and it works great. It came with a little tube of lube.DON'T GET THE WEATHER TAMER ALSO ! Thats were my wear is coming from ! also I was in a shoot 2 weeks ago rain a lot I watched that thing bounce the whole way back on my cable rod! Going back to a hoyt slide ..
