I'm considering making a Rogue/Monk. Are you gimping unarmed combat and unarmed AC the more rogue levels you take? So that means I'm locked in to TWF (which I'm fine with) but armored AC??? Does it even make sense to mix the two really?

So...what builds and split can you recommend? Could be a Rogue/Monk.

And a question: How does damage output of unarmored compare to TWF. What are the pros and cons?
