All three of ya, go look into Venture snowboards. All they do is make stiff freeride decks. They are some of the best people in the industry.
If nothing strikes your fancy there I'd personally point you at the Highlife, Salomon Mans Board or a K2 Ultra Dream. All will do what your looking for but with different approaches. The Highlife is the high speed tank, power all the time. The K2 is more of the surf/skate influenced freerider. And the Mans sits somewhere in the middle. Aggressive and precise when you push it, lazy if you get lazy.
