I know most people on here don't use this device. I know one that does and loves it so I was looking at it a lot at the show and love the idea. I think being able to walk out the limb using the wrap is a great idea and understand the limitation of it not being self tending. However I was wondering about the limitation of resetting the rope with such a device. Can you advance your rope or do you have to hit that high crotch with your throwline? I understand that working with the single line ascent you don't have to isolate crotches and that makes it easier when setting your line higher but is there a way to advance this line higher and still be safe?
