I ride as much park as I can, but I also mix in alot of groomed runs with my gf.. The Evo has been pretty perfect but it definitely takes alot of work to hold an edge anywhere over 40mph.. It's also softened up quite a bit as its broken in. I have a small core shot on the base near the edge and no matter how many times I Ptex it, the Ptex comes right out after a few runs. I LOVE this board, but I know it's getting close to retirement. It probably has about 45 days on it, but I've beaten the crap out of it.. Tree bonks, running over rocks , etc.
I prefer hybrid camber .. Specially NS type camber profile. I've ridden flat bases ( Omatic extr txtr and ride Buckwild and they just felt lifeless to me) and I've ridden camber and full rocker.. I have a stiff full rockered pipe deck, and sold my cambered burton primo to a friend. I don't miss camber, but I do miss the kind of edge hold it had. I really don't like full rocker as I just feel it's really limited and loses alot of pop.. More than likely if I ever catch a pow day that'd be my pow stick.
