Herefords take a knock at the sale barn, a red hide thing. I'm sure there is more to the knock than the red hide, marbling factor, or the lack of, is one I'm sure. Horns take a knock also. But you can't beat their temperment.
Just butchered a steer, grained him up for 90 or so days, hung for 14 days..... I couldn't be happier with the tenderness, taste and quality.
