To increase yield you got to cut back on the fat. Thats why the selects to no rolls are more popular with them who peddles it for a living that are the old fat choice briskets like we like. You increase the yield a bunch too by hand picking as opposed to buying by the case. Never know what you get on that deal..could be like a box of chocolates. Phosphate injection should also help as it tends to make the meat hang onto moisture. Can change up the texture radically. Make it taste like steak.
