In reply to LakesWinter:
> I'd have my axe on a wrist leash for an AD route, spring leashes are a pain in the arse when not climbing steep stuff and if you drop your axe you drop your hand as a mate of mine once said.
Definitely, I would use leashes up to D+ and probably beyond.
This quasi-religious belief that leashes are the work of the devil is naive in the extreme, they work well in a lot of situations, certainly a lot better than the horrible sight of an axe not attached at all, especially one that doesn't seem to have much of a handle and is doing very little good.
Agree with most of the comments about short-roping as well, especially when troging along a glacier. Why would you not have as much rope run out as possible?
Re the video, it makes me feel distinctly queasy, but that just seems to be the standard effect of helmet mounted cameras.
