Double postage, oops...
I'm like 95% sure the reason he's on Seths in a lot of shots you will see is because they were shot way, way early and the Bents weren't available to the team with retail topsheets (let's face it, half of ski films is marketing next year's products). Or at least I happen to know that was the case with the Niseko segment in The Way I See It.
All the other K2 team riders are on the Bents though.
I've skied the Hellbent in crud and wet slushy spring snow, if anything it's even better than the old one. It's a little stiffer and perhaps a little livelier - they've added carbon stringers which give it a bit more pop.
Basically you just point it at anything you like, lean sliiiiightly back and go for it. They go over small trees, small people and death cookies the size of basketballs without any hesitation.
