In reply to adamki:
Have you done Vector lately !
As stated on the other post, BMC volunteers such as yourself have done a lot of gardening work on Bwlch Y Moch and opened up some realy nice forgotten/lost routes, also the tree surgeon has cut down/trimed many of the Sychamores which obscured the bottom of many routes.
I think the new guidebook will be better than the last one, with better descriptions of approach and of the routes themselves !
I would be in favour of some kind of markers at the botom of each buttress as I know that finding the buttress can be a bit of an epic at times.
