In the second video of the Candide Invite on skipass, the first guy (who is he?) does a cab cork 7 right-handed mute to left-handed mute and even changes which ski is on top in between. I hope we see more of this.
I think it was over the big hip at the Mt. Hood Superpark a few years back, if I remember right.
Anyway, I haven't seen Cosco's trick yet, but Loic Collomb-Patton's sw 7 mute to reverse mute is def. one of the sickest things ive ever seen done on skis.
