I did 3 days with them in February '05, and I can't say enough great things. Very well organised, great friendly and obviously very skilled guides. Despite not having any new snow for 3 or 4 weeks, we always had untouched terrain. I lucked out and got 3 straight days of gorgeous sunny weather with clear skies, but if you end up with shittier conditions they do have a bunch of lower altitude terrain (mostly treed) that they can still access on poor weather days. If you can spare the cash, it's an awesome trip, you won't regret it.
Their "Heli-plex" also has a pretty good menu for dinner, not too pricey, and very good food. Some of the best wings I've ever had, and lots of other great fare (steak, venison, pasta, fish, generally something for everyone).
