re: Anything better than sawtooth oaks?

Sawtooths aren’t native and can have issues with pests and disease. Most I’ve seen planted haven’t done well long term, but that’s not to say they can’t.

Since you’ve got a few acres I would look at getting a package of a few different types from nativ nurseries, they give info on what grows well in what type of soil conditions and that would be the biggest factor for me. A healthy tree is gonna grow faster and produce more and sooner, so getting a few types that produce well on your site will give the best chance at having consistent mast every year, and hedges against one or the other dying out.
