re: Ellison's, just a reminder that the Attic bolts have recently been determined to be questionable and their use is discouraged. But if you live way out on the edge and still want to use them, and a 600' rope, tie a small knot and be prepared to tie a piece of webbing or something to the bottom of the rope as it should reach when it's stretched/loaded but may not when it's empty. It's hard to climb a rope you can't reach. ;-) Don't ask how I know this... The best option with 600' of rope is to rig the Balcony.
re: 'drinas, I've never been but someday I hope I'm lucky enough to be able to do it with someone that has Petzl Vector or a similar low-stretch rope.
