Looks like he's running a white Rockshox Lyrik to me(160mm or 170mm). I love mine! Zink and Semenuk do ride for SRAM no? Semenuk is rocking one too in black.
I like the early Warren Miller style, Tilt-into-the-Mountain-to-make-it-look-STEEPer Camera Angle (note the 'verticle' lift tower?) This pic Did NOT Need it... But, it makes the drop look tougher than it really is!!! I still won't attempt it, even if you tilt the camera the 'easy' way...
