In reply to all:
Hmm… so far, 4 against, 1 for, 1 neutral. I'm surprised, frankly, since there's already a lower-off of sorts at the top out to the climb (which itself is almost completely bolted) - just doesn't happen to be a safe one. So it would be more of a like-for-like replacement than a new installation.
While we're on the subject, there's some good harder sport climbs at PQ which are rather neglected (in fact they're almost never done). I'm sure part of the deterrent is the uncertain situation with finishing and lowering off (to put it mildly). One or two strategically placed abseil stations would help to save the climbs in question from complete neglect and obscurity.
BTW my interest here is that I am putting together a chapter on PQ for the next guidebook (along with several other crags in the area), and am just trying to get all these sorts of issues addressed now, as well as reclimbing/ressurecting routes, assessing grades, clearing areas under climbs, pruning brambles, taking out litter, etc, etc. All of which voluntary. I'm not looking for a medal or anything - I only mention it in the hope of forestalling any further snide remarks about finding something better to do with my time.
At the end of the day, nobody need worry, I'm not going to wade in and place bolts against the general consensus.
