Hey, Lyndon.
It sounds like he is talking about the descender, not the knot.
The problem with the figure 8 descender is that it twists the rope.
Since caving rope is a bunch of parallel fibers encased in a sheath,
going through the figure 8 will impart a twist on these and in the end
(after repeated use with a figure of 8) you end up with a rope that
kinks by itself.
It is a compact and lightweight descender, convenient for nuisance
drops, on short pieces of rope for which you don't care much.

Everybody else appeared to use a rock-climbers tiny Figure-8. ( I
think most caver's would agree that this
type of Figure-8 is not proper vertical equipment for caving. )
Can someone on this list knowledgeable with vertical caving please explain to
me why so?
Thanks.
