14 hours of smoke time and these are done! I didn't think about it before but the smaller size of the casings definitely reduced the cook time. Turned up to 175* and rotated the rack before bed, then woke up at 1am to check them. Smoker was at 150* and internal temps hadn't moved a ton so I cranked it to 200* from my bed...spending the extra $$ on the wifi/bluetooth capable smoker was worth it in that moment!
I was going to wake up an hour later to make sure the smoker wasn't getting too hot but slept through that alarm and woke up at 4am to a 200* smoker and the casings in the back right corner at 170* already

Haven't cut into them yet but I kept all 6-8 of them separate from the ones still under 150*.
Lowered back to 175* and drifted in and out of sleep for a while. Rotated the rack a few times and the other 28-30 got up to right around 154*. Did the water soak and they've been on paper towels in the fridge drying all day. It's delicious. Time to vac seal, just in time to take home a bunch for Christmas gifts!
Thanks for the detailed recipe 92xj, it was plenty easy to follow and the results are well worth the effort.
