Although I do not often make monk guides, support monk is something I'm quite familiar with as in the past I always ran a support monk in the group and played with one of the best monk players on the US servers that some of you may remember (scrapz) and we often discussed optimization for support monk in the past.
Here's my optimization for support monk for TX speed farming with the incorporation of Magic Find.
I use something very similar, however I don't use any generator at all...use Blinding Flash: Soothing Light, Exalted Soul passive instead of Chants...as I don't have much need to be casting mantra and would rather have a larger pool to draw upon, and use the cold dashing strike for the dodge since with In-Geom active 100% of the time I'll just take the free dodge.
Question, do you use a diamond or a topaz in helm? From running a red gem in speeds I doubt one would need the CDR with obsidian...
