RE: Release question???
YES: I used to a "Bulldog" brand release as well as another I can't remember the name of that I sold in my shop that used the same rope however it was doubled. It went around the release just like a string except leave both ends then rup up and through whatever it uses for a stop and again leave both together then tie off with a half hitch I think it's called. Very simple.
I used to have a local guy that madea release and sold them to folks. Slick working thing. It used a single length of this rope ran through a length of heater hose, then through a round leather fob and tied off to a washer. Never heard of anyone getting their nose broken!
