Correct me if I'm wrong, but I think the Bent Chetlers are meant more for hard-charging than the Opus, Pettitor, Obsethed, etc. That's what I've heard anyway. I'm sure they can be playful and a little buttery, but not as much as the aforementioned skis.
I have the 2011 Obsethed and just bought the 2012 Bent Chetlers (haven't skied on them yet) and the Obsethed has a bit of a softer flex.
