I saw some pics yesterday of Angus X Brahman F1s that had a lighter, almost brown, around the belly and back. Some even had really faint striping. That was for me but I question if there isnt a little red angus it that black angus's background.
I saw a really fancy tigerstripe heifer with a bald face bring $2.3250 per lb yesterday. She weighed 565 lbs. There was a another high percentage Brahman heifer (close to a purebred). She weighed 555 and brought $2.20 per lb. You don't see these kind with this quality very often.
