In reply to ed_simmons: I have used them for an advanced winter skills course in Scotland. I thought it was fantastic! The group sizes were small. Usually 2:1 with a guide. The guide I had was called Max Hunter. He was brilliant! He didn't really care what the course was called. He just asked what we wanted to learn or have a go at and then we did it. The hotel we stayed in was nice. The room mate wasn't! I have never heard anyone snore like that. The snoring was my only complaint of the trip. Everything was well organized and professional. I would use them again if I wanted to learn a new skill.
