In reply to Luke90:
I spoke to the Mammut Uk sales rep.
I said I would be really interested in them for instructing, I asked some questioned about belaying from the loops as well as tying in.
I have to say that I was please with the speed of reply and the info that I recieved, the only bit I can say that let it down was the price.
However if father christmas wants to get me a late christmas present I don't mind waiting
