Moss, I love that cinch method. I've been using it more and more as a means of managing less line for SRT climbing. Unless I plan to use my 200' hank for extended base anchor climbs, I'll choose my 60', 80', or 100' lines. The only difference is that I'm using an oval link in the eye of the butterfly to capture the the line. This allows me to commit to a cinch even if the tail cannot be loaded into the butterfly from the ground. I other words, if it gets to a point where I'm still pulling throwline when the butterfly is about to leave the ground, I can pop the throwline into the oval link and continue to pull. The tail of the line eventually passes through the oval link and continues towards you. A delta link can be used to allow for a bulkier splice to pass rough reliably.
PS, I'm sure you already know this. You ARE the man!
