I smoked one rack each tonight of Spare and Baby Back. I smoked the spares for 6 hours and smoked the baby backs for 5 hours. 225 degrees the whole time. My spares has nice pull back and we’re perfect. However, the baby backs didn’t really have much pull back and seemed like they could have cooked longer. Should I have gone 6 hours on the baby backs too? I thought they cooked faster than spares. Smoked on my Pitboss and didn’t wrap at all on this smoke.
