After all that I am still curious if blasting pulled or chopped pork with heavy smoke before turn in really helps with smoke flavor. As far as the rules go I don’t see it any different than those who use their smokers to “rest” meat or keep it warm but I just can’t really see getting a full smoke flavor by just blasting it.
My guess is that they really put it in there to heat it up after pulling, but, there is a lot of "new" surface area that is opened up once the meat is pulled, and that may be able to take on additional smoke flavor.
