Also are you complaining about not getting bark AND using foil? Those two don't go together so well IMO
. So try kicking the temps up in the drum and avoiding the foil. I have only smoked about 20 briskets in the drum now and I had to use foil one time (had a catering gig and they were taking tOOOOOOO long to get done!) and the bark wasn't very good at all compared to my normal anti-foil method
