so the hitchclimber isnt all that important for this. this is a lot simpler and does the sam thing really. I cant believe I hadnt thought of this before.
going back to old school and you can advance a pulley just fine.
thats simply a blakes hitch with a bowline tied in the bridge to tend it. duh. tie the bowline so the rabbit goes down the hole and then back up the hole to complete the blakes or taughtline.
for the bottom part, there are many ways that you can set it up but I think that combo HC and fixe is about as slick as it gets.
