Can't say I agree with you there Jez.
Soft skills are of course important, and generally will be sufficient in talking someone down something that they perceive to be difficult, but sometimes members of the public react in a way that you haven't anticipated, like my client suddenly becoming scared on the tourist track down the Ben. She got up it fine, and really enjoyed the ascent, but in misty conditions, which came in on the way down, she thought it was the scariest place on earth. That situation was nothing to do with me as the leader making an error.
The same can be said for my client needing a rope on Ladhar Bheinn. I've walked that ridge over 30 times with client groups and never had anyone freak out on that rocky step. However, on that day the client needed it, and if you know Ladhar Bheinn you'll appreciate that it is much simpler to continue down that ridge to the Mam Barrisdale than to try to find another route down or reverse the route back over the summit.
It is for the occasional instances such as these that MLs are taught about the basics of ropework. Unfortunately some people see it as a matter of pride that they have never had to use one as an ML. I see that attitude as potentially leading to an accident if the ML is too proud to get the rope out.
I do agree that in many cases a sling can be just as useful as the rope for confidence though. However, as you know, for ML a rope is the required piece of kit, not a sling.
