If you're going back to the Kootenays, why go back to Kimberley? It's by far the weakest resort in the area. While you are there, check out Whitewater, Fernie, Red Mountain, Castle Mountain or even Whitefish Montana. Those places get a SERIOUS amount of snow (800-1200cm each year).
As for a new board I'm an advocate of supporting SNOWBOARD COMPANIES. Not ski companies that have their snowboard division. A few off the top of my head are: lib-tech, gnu, capita, never summer, rome, dinosaurs will die, stepchild, endeavor. Those companies also all make GREAT boards.
You'll probably want something in the 155-158 range.
