To be honest with you, I haven't skied them yet. PNW is blowing my ass for snow, which is not working out too well for it.
From riding the steezes before, along with other similar skis, I imagine that it will be a bit squirrelly, but will be much more fun what I am looking for in a ski.
I have ridden the steezes before mounted at classic and modern and they were awesome. Super solid ski with an amazing amount of response for a ski its size, but still able to have a lot of fun on it. If you are looking to have something that will be fun switch, and pretty much everywhere all mountain, yet excel in powder, I would say mount it anywhere from Modern to Addicted. Classic mount is an insane amount back, so that is out of the question.
If I were you I would go for addicted. (+1 of addicted should be just fine).
