Selecting seed corn

[greg]

What do you use as a guiding principle when choosing seed corn? There is a range of choices, from conventional hybrids to fully stacked hybrids. Yield potential is usually the first thing that comes to mind for me.

I'm an heirloom grower, so it's not exactly the same, but potential yield is always the first thing I look at too. Why bother growing something that will take up resources, like water and the soils nutrients, if it won't give more than it takes? Which hybrid do you usually grow, @greg?
