Lookin good No Wake! I use the same times for bb's or spares. looks like ya be doin spares.I would suggest to smoke em at 225-245 for 2 hrs, spritz with your favorite mop, another 1/2 hr in the smoke, then foil(spritz again before ya close the foil, back in the smoker for 1 1/2 hrs in the foil, and then take a peak at them(take the packets right off the pit and check em) I f they look tender and the pullback is good, then carefully place them back on the pit and glaze with a mixture of your favorite sauce,cut about 1/3 with the juice from the foil
(don't tell anyone about that) and then continue the smoke for another 1/2 hr to 1 hr. maybe an addition to the glaze after the first glaze has set.
should work out good, especially if ya got a good batch of spares, and a decent rub on em.
