Save yourself some money and buy my freeride deck:

171 Steepwater Steep, ~11m side-cut, 25cm waist, very little camber so it's damp, the core is THICK so it's stiff like a carving board. I believe it has P-Tex sidewalls and top sheet. It's too stiff for me for a free ride deck, I needed something softer and now I ride it's little brother, a 164.
In comparison, the 164 replaces a Burton Supermodel 163 and the Steepwater is about 10x more capable as a carving board. The bigger radius side-cut and the stiffness and dampness of the board allow me to pull off some really bad impressions of the Pureboarding/Eurocarve style all while being able to slide the board around like a typical freeride. I have not taken it in the powder, but considering the original purpose of the board, I have no doubt that this can handle the task better than any mainstream board out there.
