With combat reflexes and improved trip and reach 20' or something he gets HEAPS of Attacks of opportunity.
With a monks belt, and boots of speed this guy hits 5 times a round plus many AoO's.
Each hit is for:

On top of all this if he takes grip of iron (Psychic power) he has a grapple modifier of +36!
He also has Pressure point Strike and Ki-straps to paralise an opponent for 1d4 rounds with a DC of 23!
