Here's my Monk Dodge Tank build, the guide explains how to solo farm Act 2 Inferno with 5 stacks of Nephelem Valor and kill Belial.
Here's the build I'm using:

Use the fastest attack speed weapon you can find (no less than 1.4 ideally), with a piece or two of Increased Attack Speed (IAS) gear you should be around 1.7 (or more, the more the better!). Keep Sweeping Wind up on large packs / elite packs, combined with Backlash damage this spec can actually kill things very quickly while still being a defensive tank build. In multi-player games, where you are solely a tank, swap Sweeping Wind for Breath of Heaven for extra survivability and healing.
