Germ - aggressive single cams are VERY hard on cables, it's the nature of the cam design. The best serving material I know of for a super durable single cam cable is Halo. Most people get 1000ish shots off a standard cable on a Mathews Apex 7, I was getting 7-8000 with the cable/string combo I was using. For absolutley 0 stretch, any good stringmaker (there are lots of them) using good tools and 452X will be rock solid. In my opinion, you need a quality 452X string/cable with Halo serving on the bottom of that cable.

With this said, Gibblet is the only person I know that is using Halo on cables.
