My guess is that you won't get the typical "pull" from the edges of the bones, and they might not be "fall off the bone" tender, but they will have that great tug that most look for. I've ran ribs similar to that, 2-2-1, 2-1.5-1, and no foil, and they've all turned out well. No foil have been my least desirable this far and I think that 2 hours in foil is too much as well and results in the ribs being over cooked. Overcooked might not be the right word, too tender might fit better. I like a tug, not pulling the ribs off the smoker and pulling a bone straight out of the rack clean.
Good luck to ya, looking forward to pictures and results!
