Strop hitch and two single runners for rappel extension

if you girth hitch a double length runner to your tie ins, put an overhand/fig8 knot right after the girth, put an overhand knot midway, clove hitch the top biner to the end, and then put the belay biner through both sides of the central knot (or instead of a central knot clove hitch the belay biner)

you now got a fairly redundant setup where if one strand gets chopped, it may still hold

this might be a consideration for areas with crap rock … namely the canadian rockies limestone

;)

That’s a neat idea, and does seem like it would be easier to untie. I use the setup that bearbreeder describes, but it stays girth hitched to my harness the whole time.

When cragging, do you remove your tether a lot? My only concern with the setup pictured is that you have to make sure and clip both the red and green runners with your belay biner and not just the red one (or you’d get some surprise extension). But properly setup it looks like a great use of gear

the main issue I see with all this is that it’s complicated.

when alpine or wall climbing you are often fatigued, and sometimes in a hurry, two states that do not go well with complicated.
