Thanks again everybody! @DFY- 3-2-1- is great for Spare Ribs. For Baby's, 2-2-1 is better at about a 230-240 degree range. I have also heard of folks doing a 2-1-1 with bb's cooking higher at about 275. Typically, spares are a little bigger than the babys and need that extra hour. Babys are smaller and dont need that extra time and you dont want to put too much smoke into the meat. The meat on BBs are a little more delicate.
