I'd read where they call that the 3-2-1 method but an hour at the last with the sauce on is just too long. It dries them out a little. 30 minutes is better. Also a little apple juice added to the foil wrap works good for the steam.
That's what I've always done also. Looking good Sammy, applewood chips?
