These are my current 5 favourite all mountain boards. Options that are solid in all conditions, that are quite balanced in the features and design.

In general for all mountain boards I favour a mid stiff flex, camber under the feet with rocker on the nose, a bit of a directional shape and some taper.

Hopefully the top 5 list changes over the next year as I ride more boards, but I still wouldn't be surprised if this list stays roughly the same.
