In my limited experience I have formulated this opinion.
If you have enough land and money to raise potloads of feeders or are planning on taking what you can get at the sale barn, keep'em black or bwf.
If you are planning on selling local freezer beef, pick out something you like and roll with them, trying to improve them as you can.
You'd be surprised at the number of different breeds and crosses that are run in your region successfully on smaller scale farms off of the main roads.
I think you will see more Angus and Hereford just about anywhere in the U S...???
