I may have given the impression in this thread
http://www.ukclimbing.com/forums/t.php?t=583347&v=1#x7729149
that I thought this was "trivial".
Having done it again, admittedly in slightly unsuitable footwear, last week, I have revised this opinion. Either it's got worse or I've become unhabituated to this kind of thing, or possibly both. Either way I would now class it as 'slightly concerning', if not actually 'mildly terrifying'.
Is it me, or is it worse than it used to be?
