I'd like to suggest that, when trading, your customer can see what is loaded on a pack animal, too, not just what the character is holding.
I suggest that a rope, which seems to be of use solely for making rafts/leashes, should be required to dress out a large kill, at least when a table is not available. You'd have to hang a kill to do the job in the wild.
I know that ropes can be used where a cord can be, but, why would one waste a more costly rope? Beyond rafts and leashes, there seems to be no useful purpose for ropes.
