Okay, I just realized that this sounds like a battle of the bulge post, but it is not.
My question is: For smoking and making pulled pork, is there significant difference between pork shoulder "picnic cut" and pork shoulder "butt"? The picnic is 99 cents/lb. and the butt is $3.19/lb. so it is an important question.
I have had great success with the butt in the past, but would like to save a little and buy the shoulder if they are interchangeable cuts. I am certain there are BBQ 'hounds out there who can guide me on this one.
