Bryan - Welcome to the forum.
The first thing to remember is that the smoke ring (SR) has absolutely nothing to do with the "taste" of your Q. And "yes" there are a couple of ways to create the smoke SR.
One is to add a coule of real-wood charcoal briquetts to thhe woodbox. The nitrates/nirtrites wil do the job.
You can also use a tad of Morton "Tender Quick" in your rubs.
Do a search on "smoke ring" up in the search function and you wil find plenty of discussion on the topic.
If you are loooking "Not" to babysit your smoker, CookShack is the only way to fly. I guarantee you'll not be disappointed - and so does CookShack. You've got 30 day to test it out and return it - risk free.
Feel free to ask more questions. This is a great forum and has a bunch of wonderful people willing to help you out most any way they can.
PS The wood doesn't "have" to weigh 4 oz. We measure our wood in oz just because it takes so little wood for the CS to do it's job. One of the hard things to get used to is not using so much wood like the amout you use in your WSM or a stick-burner.
