In reply to neil wolstencroft: I did a 5-day course there when I first started climbing and it was excellent. We travelled quite widely over the week, from the North East sea cliffs to Craig y Barns at Dunkeld. The instructor - student ratio of 1:2 meant that you spent lots of time climbing and I learned a lot in a short space of time, going from no real climbing experience at the start of the week to leading (ok, only at VDiff) by the end.It also meant that you could ask the instructor to cover what you wanted: some people on my course said they wanted to learn to lead easy stuff, others wanted to be able to second harder things. I guess from your post you are looking at the advanced course, there was one of those running when I was there and I know the people on it found it very good.
