And that would mean a stuck rope, which is a problem much bigger than losing a piece of perlon cord.
Those are one of the first things that came to mind. Using a loose strand of rope to block a sling, sketchy. Then, even without ice involved, I cannot imagine the loop of rope easily sliding through the end of the tightened sling; I'd assume it would get stuck completely once the end of the rope loop cinches tight into the sling loop. Anyone happen to know if this has been tried out?

I'm with Darwin on this one
