Borrowed from world-cup race skis, two different radii on the one ski - a tighter radius forward of the boot centre coupled with a 20% larger sidecut behind - increases the edge-to-edge responsiveness so you can carve short turns whilst retaining high speed stability and control through the tail of the ski.
Paulownia is a very light hardwood that is stable and easy to machine. Cores made with this material are lighter than Balsa/Flax cores, but are more expensive and require a lamination layer such as carbon-fibre to improve responsiveness.
Our standard core material. Poplar is a medium-weight, damp, vibration-absorbing softwood. Ash is a heavier hardwood that compliments the Poplar by increasing stiffness, responsiveness and providing a solid base for the binding screws.
