You are going to get an array of answers, but to me...I always by CAB which is choice or top third of choice. I think the end product is better. However, if you inject I do not think it makes that big of a deal and the price diff may not be worth it. I use KOSMOS beef injection, which is somewhat new but making big news. I have tried them all, but this is top notch. His prices are very reasonable. The injection will def. add flavor and keep the brisket moist...not overpowering but worth trying. When it comes to brisket, fat cap up/down foil/not..ask ten people...you will prob get ten diff answers. There is not a right/wrong if you and the people you are cooking for like it..its all good. But I would "experiment" to find what fits your needs. Let us know your results.
