Who should I vote for on super tuesday?

I am going back and forth between Huckabee and Romney. Who should I go for? I don't like Rudy, or McCain. I want conservative (and don't write ron paul he is a joke!) Some say Romney is more conservative than Huckabee, but I am not sure about Romneys abortion record. So who is going to be more like Reagan? If you could point out some good and bad for both...thanks!
