Apparently my butcher only gets in CAB packers for 2.30/lb. and average weight is 20 lbs!!!! Can I even fit that in my 18.5"? How freaking long will that take to cook? I have been extremely impressed with the quality of meat from this guy, so I want to stay with him and build a relationship, but 20 lbs. seems like overkill. </div></BLOCKQUOTE>
That's a big brisket!! Squeeze it between the grates to make a 'hump' in the center, after a couple hours into the cook, it will shrink and straighten itself out.
If it were me, I would separate the point from the flat and cook the point on the bottom until the flat is done and then put the point back on top to finish. I almost always separate packer briskets before smoking anyways, regardless of their size.
