Of course there are disadvantages with rocker boards, just like there are disadvantages with cambered boards. Rocker boards can be good, but are just not as good as cambered boards for high speed riding. On steep, icy, hard packed terrain, a cambered board is just plain easier to control and much better at it. I don't care if the rocker board has MTX, Neversummer recurve, whatever. Really though, rocker is a lot of fun and works for most everything. If you are riding hard boots, or fall and you die terrain, then rocker is probably not for you. Otherwise, you'll have to look at what you like to ride and how rocker relates to that. For myself I can go either way.
