Shoulders vs butts yield ?

[big blue bbq]

For catering and vending purposes I was just wondering what is used the most Shoulders or Butts. I know you have more cost tied up in wood/pellets for shoulders since they take longer, but what is the meat yield difference?

[Bbq Bubba]

60ish% from butts, MUCH less than that for whole shoulders.
With the whole shoulder you have more bone, skin, fat that lower your yield.

[Jacked UP BBQ]

55 on average from butts, about 35 on shoulders.

I only do the Butts, and figure 50-60% yield.
