I've been needing to make an adjustable RL ever since I made my first hammock....but instead I made one for my second hammock. Instead of making a whoopie, I made a UCR with 1/2" fixed loops on the ends and length when fully extended about 100". I've made whoopies but this is the first time making a UCR. Very simple to make. I followed TheBrewGuy's instructions for making the fix loops with locked brummels on his "How to make Whoopie Slings" vid and then just made the UCR. This will be so much nicer then the way I've been doing it, which was just a small bowline on one end and a round turn and a few half-hitches on the other with enough tail to allow for adjusting.....works but not the best way to do it.
