I'd go with a broadcast feeder for sure. Like someone said above, I would not start feeding corn now if you haven't been. Since deer aren't used to the corn that could easily starve even with a belly full of corn. In this cold wet weather, if you pile up corn the bottom of pile will get mildew on it and be inedible, therefor wasting your corn. A broadcast feeder will keep the corn fresh and spread it over a large area.
