I have a team of monks, 1 BrewMaster, 2 Windwalker and 2 Mistweaver. They are only 85, but I have had no problem with that setup.
Hardly have to do any manual healing at all, apart from the occasional chi bubble before a boss pull.

I am planning on taking that team through to 90 Heroics, and based on how they've gone so far (and assuming I can get decent gear) I don't foresee too many problems.

Don't have footage though, sorry, my comp craps out when I try to fraps.
