OK, Cam. You convinced me. I will try my next batch in the SI.
You are right that the Chief's (big and Small) have trouble maintaining temperatures in colder temps. That is the main reason I got my new smoker. For the most part all the Chief's do is impart smoke. For anything other than jerky, stix, and fish, you have to finish everything else in the oven/grill after the smoke has been applied.
Thus the reason I have never been able to do a pork butt or a brisket.
No problems with that now. I just need to find the time and money to pay for all of this meat that I want to smoke.
