I will be using my new 120 to begin smoking my brisket recipe that I have used for years in my traditional stick burner pits. I have mastered the Pork Butt in the 120. The efficiency is out of this world. I smoke from 225 to 250 using 13 - 16 lbs briskets. Can someone give me some ideas on smoke time, wrap time and total time for the cook using the 120? Thanks for any assistance.
