re: when to foil ...
In addition, some of the best ribs I have done, (instead of doing the last stage, either opening the foil or removing from the foil then return to the smoker and heat to firm up and crust a little). Instead I leave them in the foil an put in holding either sealed in foil then plastic wrap then towels in cooler or if you cooker can be used as a holding vessel just leave them there in foil turn the heat down to 160º. When ready to serve remove the rib racks and put on med heat BBQ grill for about 5 min. on ea. side, this is where I sauce them then serve. You can't do this last step if you ribs are overcooked and falling off the bone! So it pays to learn how tender the rib needs to be before foiling...
With practice your results will continually improve!
