That first batch of Polar boards that was available in the US was the MDCN wood. The one I had was pretty sturdy, good quality wood. The shape was a little off though. As far as the US-Made Polar boards, I don't like them. I had a couple of Hjalte's boards and they were so so flat. The nose and tail weren't arched high enough either. They got soggy pretty quickly. Generator has two different wood qualities to pick from, I wonder if Polar is using the lower quality wood.
