Which team has the best 1-2 at the top of their rotation?

there are a number of good 1-2's. carpenter / wainwright, and lince / cain seem the 2 obvious choices. hernandez / lee could be there, but can't be right now because of lee's status. halladay / hamels might be except that hamels had an atrocious 2009. a darkhorse for this year would be hanson / jurrjens of the braves.
