This may be old news, but just in case...

I was having some some work done on my guardian today and, during the process, the guy at the shop realized that my cables had started cutting through the plastic cable slide. Looked like a good 1/4". Don't know if anyone has addressed this problem previously, but if it hadn't been caught and the bow had been at full draw when the cables went completely through, it could have caused some nasty problems. Anyway, it looks like the factory cable slide is made of an inferior plastic. It may be a problem specific to my bow, but just wanted to pass it along. It might be worth checking.
