I was in the yard shooting a little this weekend and noticed a little wear on one of the cables on my bow. The wear is mostly in the serving area where the cable rolls up on the cam while drawing. I am not sure of the proper name for this cable. My terms in describing the problem may not be exact. The bow is a Bear Instinct. It is a couple years old.
Could it be that I am not waxing enough in this area? How far should I let it go before I start thinking about new cables and strings?

Thank god for kids.
