In reply to Al Evans:
> (In reply to Mark Kemball) Always a good idea, miles more impotrtant than the earlier thread about the prussik back up.
Just goes to show that years of climbing experience don't necessarily equate to good understanding of ropework!
I can agree that use or otherwise of a prusik (Wun Ess!!!) is down to individial preference, but you and Bruce are way off mark if you think that in general it increases the danger of an accident.
However, the idea that tying a stopper in a fig 8 knot is more likely to increase safety than backing up an abseil with a prusik is daft. If the knot was a bowline, I'd agree 100%, but if the tail on the 8 is long enough, the stopper's superfluous.
Personally, I use an Edwards bowline most of the time, without a stopper, so it's academic to me.
