Replying to Look Pivot for Powder skis?

I have some new Black Crows Atris Birdie (107mm underfoot). I am using these as my pow, steeps, off piste ski and am in need of a binding. I have been a fan of the Rossi fks which I have on my park ski. So naturally I'm looking at the Look Pivot 14, but I've discovered these aren't the most advised binding for pow skis due to the lateral movement and difficulty in getting the skis back on in deep snow. Should I be looking at a Tyrolia or something else?
