I will teach you SirPorks, I can do it all. of course, I am not from North Carolina, so what do I know about BBQ :tongue:
It is all about temperature control, I also think you can get it done in 3 hours, with a little change for glazing. They will have some pull if you don't foil, but, it can be done without foil.
All joking aside, I bet if you go St. Louis cut, pull the membrane, relief cut the bones a little from the underside, go hot, open cooker for 30 minutes on the bone side, start the rendering process, then close it up, let it ride for 2.5 hours, adding moisture and using a low sugar rub, you can get them tender, then hit them with a sweet heat sauce, you can get them there. I need to try this.
