Ok, I just started the second 2 hours on 2 racks of baby back. Had good smoke at 225 for the first 2 hours w/ jeffs rub. Have em wrapped up in tin foil w/ AJ for 2 hours. WHen I do the last hour to firm them back up should I bother w/ smoke at this point or have they taken on as much as needed. I am using a gas gosm and not wood.
