In reply to S Ramsay:
I've used P2P. They were reasonable but by no means awesome.
Me and the missus were booked onto a level 2 session, which they then merged with a level 1 session. Clearly there's a difference between l1 and l2, so it was a bit of a stop/go morning for us and a baptism of fire for the two L1s.
In the end both the level 1s retired injured and so the day sped up a bit. Which was better for us but frankly appalling for the two level 1 people who were dragged out of their comfort zone to the extent that they broke.
In the afternoon the guide took us to a completely different part of the mountain which was completely in the cloud, unlike where we had been. I thought this a little odd given that they are supposed to be experts in the area.
The cloud and poor vis was a contributory factor in the second injury.
