Love my summit but I guess I am one of those cheap bast##ds that will only replace them when I have too. I look at mine every year and although there is some wear on the plastic/rubber cable of my summit viper,the cables are in perfect condition.

I also check the frame of mine every year. I bought the new viper and took it home and used it once and found a cracked seam on the platform which "dicks" replaced without question. So it does pay to look over your equipment every year including your bow limbs, cables and safety harness!!!! I have heard too many stories on this site of people falling out of trees and I dont want to be one of those few!!!!
