I'm starting a breeding project and need some help finding the biggest barred rocks

[El Exorcisto]

The title says it all. I want to cross the biggest barred rock rooster I can find to black ameraucana hens. The goal is to make a dual purpose bird, sexable at hatching, with beard and pea comb to deal with New York winters on the top of a mountain. What breeders make the biggest barred rocks around?
