You can ride anything in pow. I took my k2 www non rocker in pow and had a blast.
However. After taking a rocker board out on a fresh pow day i dont ever wanna ride another traditional camber boardthrough pow ever again. So much more fun when you dont have to lean back as much. That being said i would try the nitro gullwing(reverse camber) or T1(zero camber) if you want nitro. Custom v rocker for burton.
I took my signal park rocker out on a fresh powder day and while it sucked at full speed on chop/groomers it excelled way better than my friends burton vapor in the pow.
