Prior was at Kirkwood today with demo's. I couldn't resist, I demo'd the Metal WCR. 183cm was the length of the one I rode.
The board is fast. Turns easy, fast edge to edge as you'd expect with a narrower board (19cm waist I think). Carves well. It didn't chatter at all for me. I weigh in at 180lbs now. I didn't have any trouble flexing the board, and I don't ride particularly aggressively. So it's gotta be soft.
Not only didn't it chatter, but I had very little slope feel at all. Kinda like driving a car and not having any road feel. Not much input came back from the board. I can see where this would be really good for a racer, but it's just not for me. I like to get feedback from the board (and from a car).
I think for some, this thing is going to be exactly the ride. But it doesn't suit me.
On the up side, I didn't have any trouble managing the length. So when I go shopping for a board next season, I'm going to look at something around 180cm. I'm seriously considering a Donek FC2 Olympic.
I also took it back after 5 or 6 runs. I wanted my Donek Axxess back!
