I made a demo video with some examples if you'd rather watch:
Basically, while the math behind stats and what-not are always important, I've found that using fast 1-handers is the most satisfying (at least as far as the beta is concerned).
Most of the end-game 1-Hand Monk items are quite fast (almost as much as daggers), so I imagine Blizzard anticipates that kind of setup. But then I look at the Daibos which are around 1.10 attacks per second... and I have a hard time believing I'll ever want to use them. Thinking about Inferno, it seems ideal to use a fast 1-Hand for spirit generation, and then a shield for the defensive bonus...
P.S. on the topic of attacks per second, does Blizz cap it at something? I would guess at level 60 with 2 super fast weapons, and a bunch of items with +speed, you'd hit a cap?
