Yep. This is who we used. First class operation. Can't say enough good things. They know their shit. And they know that area like the back of their hand.
@Born to Run regarding ability, they did a great job of tailoring the trip according to ability. I'm a good, but not great, skier. I can handle blacks and moguls, but I'm not super fluid and I don't do the double black diamond stuff. I had skied in powder before, but not like that. It took some getting used to. For example, I veered off to the side and the chopper pick-up location on one run, and took my skis off and sank to my chest in powder. By the third run, I was more comfortable and started taking more aggressive lines that actually helped all around. If I did it again, it would be a completely different mindset.
The group that we were paired with (husband and wife) were amazing skiers. The husband skied competitively in his younger days. We had two runs where the chopper dropped me and my buddy off at the normal launch point, then took the guide and the two of them up to a more difficult segment that ran down to us. It was a blast to watch them carve up those steep areas between rocks.
To me, the most critical part is physical aptitude. If you can't ski all day, or if you're out of shape, don't do it. You need to be ready for getting after it to make the trip enjoyable. So, to summarize, if you're a high-intermediate skier in good shape, you'll be fine. Anything less than that, and I don't think it would be very enjoyable.
