IMO:
If terminal, Anazazi and Gaurus have got some good ideas (maybe include Limi in there).
If you're going to keep every single heifer made, then I'd say something different (Aubrac, etc.).
If everything is going through the sale barn, I'd say something different (red or black Angus, etc.).
If you live way (!!) north, I'd use something proven to do real well up north that hairs up good to help out there (Galloway, Aubrac, etc).
If you live way south, I'd use something with proven parasite resistance, heat resistance (Mashona, Tuli, Southpoll, Senepol, Barzona, Brahma, Brangus, etc).
If you want lots of really cool colors, get a blue roan shorthorn bull or some sparkly longhorn bull with lots of chrome and color.
It all depends on your objectives.
