So was I! Becky Jones is on the list; I'd have thought she'd pipe
up. I did ask the PMI folks about the larger caving rope -- which
they had dubbed "PIT Glow." It was discontinued in 2006 due to
poor sales (i.e., too expensive).

Diana - I'm not of the opinion that it's enough light to do damage. :-)
But speaking of the history of caving rope -
I saw the transition of nylon parachute lines (550 cord) to dacron and later
to kevlar. Dacron is still.
Dacron has some fine qualities - viscous damping for instance. Not

At one time, cavers did use polypropylene ropes to some degree, primarily for prusik knots. When I first started caving in 1968, most cavers in our grotto ascended with prusik knots instead of mechanical ascenders. Jumars existed, but they were too expensive for most of us university student cavers
