Next year I think I'll try to arrange a group of 8. It's a little hard getting thrown into a group where you don't know a lot of the people. Thankfully, we had people sit out that didn't like it.
The conditions I skied were different than Pinhed's. The avalanche danger was pretty high (we were there the week before.) Most of the stuff we skied was in or near trees, most of the slopes were less than 40 degrees. But all of the snow was powder, usually knee to waist deep. I used a pair of Pocket Rockets and they worked fine. I wouldn't have wanted a normal alpine ski.
Oh, another tip - since they operate Thu - Sun, it seems like Thu might be the best day to go. You have the potential of getting the best tracks.
