Usually get the 2-packers from Costco. They are boneless, and together they weigh in at 12-18lbs.
Just did one (2) yesterday, it was the smallest I could find and it was 14.47 lbs. ended up getting a little over 12 lbs finished.
Only four of us at home now, but the left overs and taking it to work is the best.
Have a graduation coming up in 3 weeks so I'm going to try and get four of those babies in my MES 40". It will be tight but I think i can make it happen.
A few pics from yesterdays smoke... oh soo good!!
Oh yeah had a brisket in there too.
Like the boneless ones because they lay out nice and you can get the rub into all the nooks and crannys easily, and they seem to cook more even.
