OK...
I ride my ANTs ducked, they are as ducked as i can get them, sidewall to sidewall. I can get some photos if you'd like.
Now i love riding duck, although on piste they take a while to get used to, your lean is on the outside of your little toe so it feels strange, but i didn't do it for piste.
In pow is fantastic, it such a natural stance, there is much less pressure on your knees and all over it feels more natural.  It hasn't worsened my skiing, if anything i feel better and more confident.
There is an argument that mounting duck can cause pre releasing because of the angle/pressure exerted on the bindings. I have never had any issues with this and will be mounting all my pow skis duck in the future...
Really consider it.
