Thanks for the response.
All helpful information.
Stumble, I like the idea of using leg muscles and will look more deeply into an ascender set up.

Mark,
A question regarding your two ratchet blocks. You mentioned disengaging the lower ratchet to come down. Do you leave the upper engaged to give you a little control coming down?
On a 2:1 set up, the fall going through the carabiner hooked to the harness with a carabiner hitch gives control coming down with the ratchet block aloft disengaged before coming down.
