Maines are like Simmentals, they WERE a dairy breed and tend toward larger frames. The Maine breed has gone more toward the show ring and the Simmental more toward the producer. Maines will throw calves with alot of white, like socks, and sides, plus the red hide. Also the Maine breed does not offer a polled gene for horns, so plan on some horned calves. I breed my Maine cross Cows to double polled PB Simmental bulls. You have to select low birth weight Maine or Simmental bulls to breed up on British breeds. The Simmental Org has the CE (Calving Ease) EPD, this weights calf shape and assistance into the picture. I think this has more value than the birth weight EPD. We have some cows that drop 100+ pound calves from AI sires, unassisted.
