Replying to Fat, Rockered, Medium flex pow ski, which one?

I am looking to get some fat pow skis with medium flex for next season. I would like for them to be rockered because I want some rockered deep pow skis, so what should I get?

The skis I have been considering are:

Moment Rubys
Line Sir Francis Bacons
Bluehouse Mavens
K2 Hellbents

Any other suggestions? What bindings should I get. I am a big fan of 4frnt bindings, but what are the best bindings for the type of ski I am looking for? Just looking for suggestions. So I can make my choice and start saving up.
