CO has been running at about 17/12/2, but has raised everytime it has folded around to him.

Button has been a call centre pre-flop, loosely calling raises and re-raises, but I haven't seen many of his hands post flop. He's running at 33/4/0.25

A call pre-flop may be a better play here, but I generally re-raise most hands out of the blinds if I'm going to play them facing a raise.
