I am doing my 2nd brisket in the wsm tonight and I have  a couple of questions.  first let me say that this is a very good (choice) brisket with nice marbeling.  I am planong to go low and slow 225 to 250.  my first question is how long should I expect I am thinking about 1.25 hours per pound.  next is does everyone think foiling is neccesary? I smoked many briskets of this quality for work years ago at 200-225 without any sort of foiling with great results, but this was with a large comercial smoker with a seperate fire box below (very even heat). Most turned out great some better. will the wsm's less even heat be a problem? I really like to keep it traditional as much as possible and skip the foil unless it will have a marked improvement.  I do not like to foil simply to speed up the process and feel that rushing the q tends to toughen the q.  what do you folks think?
