Bob, I'm curious how you'd bail with 30' of webbing and no harness?
I often carry a 70' 7mil for backcountry belays (mostly avi slope testing/jumping, or belaying to dig a pit), and a couple slings and biners for anchoring to trees. Trying to go light, so wouldn't bring much. Thats enough gear to rig one sling for a waist loop, and one for a single leg loop (I like to be able to breathe
, and rappel; barebones rappel device being a single locking biner, and use a munter hitch; though I'd usually carry an ATC. So if I want to be able to retrieve the rope, could do a 35' rappel; maybe 40 feet with rope stretch.
They make such superlight locking biners these days; and quickdraw biners; works of art.
