Others may disagree, but I think it's more likely that you can get a bright punchy tone on a "dark" sax with a high-baffled mouthpiece, than to be able to get a warm, dark and buttery tone on bright horn using a "dark" mouthpiece. The latter might really be better described as muddy.
So, I'd say that if for whatever reason, you're restricting your choice to a cannonball, get the raven and try pairing it up with a JodyJazz DV or a baffled Ron Coelho (RPC) piece to give it some edge when you need it.
