I would image that neither of those devices are likely to work on 9mm double ropes, which is what I normally use and have had to ascend. And come to think of it, I don't use a prusik. I use a klemheist, which is even harder to spell.
So, I 'klemheisted' after I got pulled off the second pitch of a climb last weekend.
I'm inventing my own climbing terminology as we go along.
