I use to have 'Super Baldy's', but we just called them 'black cows with some ear' or 'half brahman half angus'. I bred them to a polled hereford bull. Good calves, but I got better calves from 1/2 angus 1/2 American charolais (not the big headed French) bred to a polled hereford bull.
Never heard them called Super Baldy's.
