I think everyone just needs to chill. BA is honest and sarcastic at the same time. Not only is he both of these things, but he's also consistent with both. Take a deep breath and relax. It's not like he's beating you up on the playground after school.
I'm not too worried about BA being able to take care of himself
Neither one of those companies are really considered that great for snowboards to my knowledge (Flow obviously is pretty famous for their bindings... Rossignol kinda got some attention this year for having A good board, haha). I understand that camber is what's familiar, but completely throwing aside the new tech after just riding those boards seems a little premature to me.
Plus, as you mentioned, your hill doesn't really have much powder (if at all). That's one of the biggest reasons to ride a rocker board.
