cancun mark:I wasnt suggesting it as standard practice mike!
I know you weren't. I was just pointing out that in some caves, I don't think a balanced rig that you can swim up would be good enough.
Didnt Rob Palmer die of a runaway descent? I cant remember the details.
From what I remember reading his buds reported last seeing him still descending and they turned for whatever reason. If I remember right they reported that he didn't appear in trouble though. Note, though, that it's just what I remember. I don't know anything about his equipment or anything. Some one like Curt B. might have a little more info.
