Hey I was just in the market for a very simular board as I too ride all mountain and live on the east coast and wanted to go from my traditianl camber wood plank I've been riding for the past 4 years to something more cutting edge. I decided to get something not on your list. The Rossignol One Magtek, I also ride alot of Ice Coast ice and this boards Magnetration was supposed to be solid it also has some decent flex to hopefully get me started in the park. But most websites say this is the one board to own if you can only own one. So I went with it, I rode this weekend and man it's way more fun to ride then my old board. Also I was riding Hunter which due to this weather was litterally and ice skating rink and I was gripping nice. Just something to look into for us east coasters. I'm sure people with way more experince then me will have some more choices.
