for 250 bones... not gonna find the "best" all mountain board, sorry mang!
But its this.... Lib Tech T.Rice pro model with C2... not cheap, but you will love it. I have two older models and they are rad. One with Magnetraction (MTX) from before rocker was a thing and one with Rocker (banana) and magnetraction BTX (banana traction).
These dudes started the rocker revolution. Dont dog MTX till you ride it.
They also make the attack banana and some other ones. But they have been doing Rice's pro model for a long time, Ive always liked em.
