I got the Cirque 22 late last season and skied four days in it. I'm completely converted. It feels like a big 22L, closer to 30. I can fit everything I need for full day tours in GTNP in it no problem. It moves more naturally with my body on the down, and I notice it less than any other pack I've owned. And on the way up my food water, etc is all available without taking the pack off. I'm fully converted, especially since with the little skin side pocket, I could potentially transition both directions without taking my pack off.
Only downside would be that if you're boot packing far with heavy skis, I'm sure it would get uncomfortable. I wouldn't hesitate to boot a few thousand feet with a 1600g ski on it, but I sure wouldn't want to be hauling around 2100g skis with Cast mounted on them or something.
