To wrap or not to wrap?

I wrap brisket w/ butcher paper and sometimes wrap ribs w/ butcher paper.  I never wrap pork shoulders.

I never wrap either one, but to each his (or her) own

On butts and briskets, I pull and wrap in heavy foil then an old towel and into a cooler till eating time.  As for wrapping during the smoker, never. Although I did go the 3-2-1 method on ribs a few years ago.  Pretty good ribs but I was not fond of the extra 'work'.
