Nice those ribs look goooood. Were you able to get a smoke ring? I cook them uncut with the slab split in half, but I think next time im going to either cook whole not split or cut each rib individually. Ive made them about 10 times on my propane cooker and once on my WSM 18.5" which I have only done 4 cooks on. There was no smoke ring when I cooked them on my WSM and very small ring,sometimes none, when I made them on propane smoker. On the WSM they cooked at 240 a majority of the cook for about 6 hours using about 5 baseball wood chunks in total, they were very tender, but I thought they lacked flavor. So I am determined to try them again.
