Final Update. Reached 190IT at around 4 hours. Wondering if opening the door to change the smoke box foil caused the rapid IT increase the last hour. I pulled, foiled and placed in a cooler for an hour.
Sauced them and caramelized on the grill. Taste was great, but seemed over done. Some pieces were tough, others were really good. I would definitely trim the fat off better next time--not tasty fat. I do not see myself doing "Boneless" Ribs (Doesn't Even Sound Right) again with this smoke plan. They were all consumed, and no one tried to cut me--all in all they were OKAY! Think I would go with pulling at 140IT, braising, saucing, and caramelizing next time.
