Whole shoulder

The pork shoulder is the entire front leg and shoulder of a hog. It consists of two portions, the boston butt (upper part of the front shoulder) and the picnic. The picnic section has the bone left in, usually. The whole thing will typically weigh about 14 to 16 pounds.

That would fit in my smoker (Americue) just fine. I'm not sure of the inside dimensions of a smokette though, the length of the shelf in particular. I'd estimate that the last whole shoulder I bought weighed 16 pounds and was about 16 or 17 inches long.

Like SkipQ says.
Comp cooks like 16 lbs and cook about 16 hrs.

Typically MIM and they do it for effect and being able to pull out different types of meat for the sitting judge.

Problem in PA will be finding someone who actually has them.

He's one before cooking.

PB is on the left side and Picnic would be the right end:

I can get those at our market in downtown Detroit. On the weekends a Pig processor has them, fresh!!! Processed Thursday sold on Saturday, cooked all day Saturday and some of Sunday squeezed into my 025. Last one I cooked was almost 20 lb's, good eats!!!

Hey Bubba, can you remember what you gave for your shoulder?

18 lb's translated to $24 and some change, so that would be about $1.34 a LB.

In this area (Toronto/Hamilton) shoulders are very common, more common than butts. Its mostly because of the Italian and other immigrants who make sausage from them, thankfully. They usually are trimmed in a certain way that they call "New York Shoulder".
Anyway, because of the demand, they usually can be bought for .99 lb to 1.30
I think smoking the whole shoulder makes for the tastiest pulled pork, but of course that may be a biased opinion.
There is nothing better coming from a smoker than a done-correctly 18 lb. shoulder

Many areas of the country,folks are concerned about what to do with 16-20 lb of meat,not understanding 50% cook loss,and the fact that pulled pork freezes well.

They also don't have a pan to cook them in their oven.

Also,The supermarkets can promote picnics for $0.89/lb,and sell the butts for $1.59.

Thus, the grocery price average of $1.30/lb is easier to achieve,and they have no loss from running the bone saw thru the shoulder,or labor.
