think about it....you could put a crab straight on a nut (but don't in order for the movement of the rope not to dislodge it) if you felt like it.
the only workings of the system as you put it are the stiching of the quickdraw. taping over to stiffen it won't affect this. the required dynamic element of the system is already provided by the rope.
