I personally believe that the answer has to do with your smoker!
Do you need that extra moisture?
Seriously you are changing a long smoke to a short smoke, why do you consider a 12 hour smoke short? LOL
If you are burning charcoal or wood, I can understand it. Cost of resources and that the moisture needed.
If you could be sure of an exact time of completion either way and needed to plan it, maybe.
But since I and currently using an electric, and don't need the moisture, don't need to worry about resources, in no hurry to finish, and love that lovely unsteamed bark. bAlthough since I got these store bought teeth the softer steam bark ain't bad.
I don't wrap, when I do it is just to increase my experience.
