Musical Cornbread
I don't like sweet cornbread usually. My grandpa was a cornbread making machine. He had several different types. Cracklin was my favorite followed by Mexican which just had jalapenos and whole kernel corn in it. Cornbread is cheap to make so if I were you I'd just start knocking out some test pans and find something you like. Being it's a brisket cook-off I'd work with that theme.
