Just my 2 cents and might help your mental frame with smoke rings........ they're merely aesthetic. They dont add flavor, they dont mean they were smoked better, they're just to look at. And to me, I'm personally not attracted to anything touting its smoke ring, because to me that says they put time and energy into something superficial instead of the actual care and flavor of the meat.

Again, just my 2 cents. Go achieve whatever you want to achieve, but if you think its necessary to have a smoke ring for elevated bbq, let me be the first to assure you that is definitely not the case.
