Serious question, Franklin style brisket over hot and fast? I ran both last month in Waco and the 12 hour cook won by a mile | BBQ Pitmasters - nhfree.com
Ran hot and fast once and the flat came out dry as a bone. Franklin style needs that low slow time to let the fat really break down and soak in. Twelve hours sounds about right for a packer that size. Trust the process and keep the temp steady around 225 to 250. Hot and fast works for some cuts but brisket rewards patience every time.
