after several rides

C3 shape feel fine. I switched from Rocker nose + Camber to that C3 and it rides without an issue.
It really handles icy slopes, though not sure if that is because it has sharp edges or because of that C3 design. I believe (my personal feel) that C3 shape gives about 25% more grip than tradition, not more.
I also would like to mention the board has soft top sheet, and after few days of riding it has bunch of chips/hangnail on sides - because of other snowboards / skies on a chairs. Wish to attach some pictures, but this form hasn't that option. However I believe it should not be a decision point to buy it or not. I bought it because I wanted to try C3 design and stiff board. It is C3 and stiff. I continue to use it for next few years at least to deeply understand that snowboard. After few rides it is just a brief overview.
Have a good snow, guys! Cheers!
