I use any rope (but there is a heavy green rope at bass pro for about $4 that works good - heavier in case the load is heavy) and actually cut off all of the caribiners, clips etc. I can't tell you how much noise these things make - i don't care if they are rubber coated etc - they all make noise and all of the serious hunters I know cut them off.
I use a peice of telephone wire.It saved my but once when I dropped my quiver!made a retreival hook very easily!
I've been doing this this year and mine gets tangled easlily and is hard to get back into working order. I'm going back to a thicker rope.
