Here's what other sites are saying:
You're right at home on the dark side of the mountain, in north faced couloirs and super deep slopes because the DarkSide Ski from K2 got you there. The Powder Rocker starts just in front of the binding, turning the tail into both a brake & an accelerator. Pressure the shovel to quickly & easily pivot the ski to scrub speed, or pressure the cambered tail for added power and acceleration. With this kind of control and stability, you find yourself holding the throttle open down any face.
