If I was your size I'd look at the Lib Tech Skunk Ape. It comes in a 157, but personally I'd go with something bigger if you like going fast. I'm 195lbs and my fresh powder day/going fast board is a 168 burton canyon. Also the Magne traction on the Skunk Ape will be great for the Canada ice. And I'm guessing you have some big feet so this board should accomodate you nicely. If you want something more park oriented look at the lib tech dark series. It's lib tech's wide park board, also with magne traction.
