The local yuppie store that carries really good, high end choice meat will order a packer for me ($2.99/lb, not bad when select is $2.49). Their steaks are fantastic, really well marbled, natural beef. After reading the post on prime brisket being better low and slow, does this apply to high end choice, or is high heat OK?? (I don't want to ruin this and have only done a few flats - most recently high heat which came out really good).
