Looks unsafe, and not fun.
I rather use kinect and super realistic snowboard in trueHD on my Durango. : )
its not for snowboarding, it's to give you feedback when you aren't balancing right in wii fit 3 *eyeroll*
Sometimes I wonder if you are a spokesman for Microsoft or just a really enthusiastic fan.
I never cared for the balance board, I don't recall anything compelling for it outside fitness games. I had more ideas for that Vitality Sensor than I ever did with the board.
If you wan't realistic snowboarding then go snowboarding...
