In reply to IOAN D:
I do see horrific top outs as being an important part of some routes. Having climbed routes in North Pembroke requiring "rabbit hole" belays and others involving tottering jenga piles I would hate that people thought I was arguing this to reduce risk or excitement.
I strongly believe that the routes mentioned "finish" a good few meters before any belays. Having climbed Balance of Power in a single pitch I can attest to both the quality of the climbing and the difficulty dealing with that last section of vertical grass.
I did not feel that the last section was an important part of the route, the intrinsic value of the routes being run out climbing on good rock.
Having also spent an hour or so on a hanging belay on The Erg (pegs mentioned in guide now all deceased) I would like to climb that route in a single pitch as it would be a lot more comfortable and a far better route.
