FYI, I did make this brine recipe last week on 2 shoulders (@$1.47 lb - cheap eatin') and I cooked them on my BGE @ 225 for almost 14 hours and the internal temp was only 175 when I took them off. I took them off early because when I put my fork in it to turn them over the roasts just basically exploded and broke apart they were so tender. I did wrap them in foil and baked them in my oven another hour at 275 and that got rid of some extra fat/grease.
I pull my meat (no pun intended - LOL) then bag up and freeze the extra. It freezes and retains the smoke very well. You just don't want to over microwave the smoke out when reheating. Over microwaving will kill the smoke flavors and leave you with plain old bland cooked pork. That's what Dickey's BBQ (BBQ chain here) did to my last and only sandwich there.
