In reply to The Lemming:
I'm confused by the 14 dislikes simply because I do not understand what the dislikes are for.
Are they for a double negative, in that they agree with the leader must not fall?
Are they for some circumstances where a leader must not fall?
Are they of the opinion that the leader must fall on every style of climbing?
Are they of the opinion that the rule does or does not apply to bouldering?
Are they my faithful band who just like to click dislike?
Basically, the clicking of dislike with the OP does not add anything to the discussion other than to confuse matters because I don't have a scooby what your views on the matter are.
As for me and my mates, we will still climb within and on the edge of our limits depending on how much enjoyment or how much we want to push our limits, but through it all there is the underlying principle that we will not climb to the point that we will intentionally fall.
Accidents happen, but we won't climb to the point of deliberate failure and fall either on trad, sport or whatever. As for bouldering, crash-mats are making this more safe, or the perception of safeness that may not actually exist just because we no longer climb with an off-cut of carpet rather than a slumberland size mattress.
