Most every "jock" I've known was a good dude. They sometimes pay me a real nice premium on my calves.
To the question, a small fraction of chi blood is desired by some commercial cattlemen, and yes there is usually a tic of chi in most good show steers. But for a high % chi, I wouldn't even know where to begin looking. I think there are a couple of ranches in southern Texas that raise the old big whites, but they arent real practical.
