You know me I'm all about "You do what makes YOU happy" But.......
If smoke rings are important why would you buy the smoker that can never make one?
Real smoke rings are a fickle bitch that can not be counted on to show up. In the volume of meat I smoke I see pork consistently taking good color but across the board beef is unpredictable. Six briskets may have good rings, six may not, and that is in the same smoke on the same night. I believe this is why fake rings look so fake they are too controlled.
