From the K2 website:
The obSETHed has a Tip and Tail 10/20 Rocker. Tip and tail sit 10 mm
off the snow and the ski contacts snow 20 cm in from the tip while
sitting flat. The traditional camber underfoot gives the ski better
versatility in all different snow conditions, especially firmer snow.
Tip rocker last year, Tip & tail rocker this year, like the Line SFBs
