Alright, guys and gals. Did a bit of research on types of MTBs, and it's looking like I need a dually.

What do I need to look for? Just pay attention to the Shimano hierarchy and aim as high as I can? Bumped my budget up a bit. Looking at some bikes from bikesdirect and bikeisland. The Gravity FSX (1.0, 2.0, 3.0) look pretty nice. But I cannot seem to find many reviews on them.

Have not looked on CL since upping the budget and deciding on dually.
