Rock Out Camber
Flat between your bindings for stability, Camber near the feet for response and a rocker on the tip/tail for pressability.
Tapered directional
Tail width is slightly tapered (2-20mm). This loosens up turning initiation and improves floatation in deeper snow without sacrificing edge hold on hardpack.
Radial
Created from a perfect circle, Radial is the classic sidecut for consistent response forward and switch.
