Welcome Brian. Congratulations on your 3D...with the stand! I tend to like things a little smokier, so I go on the high end of the wood recommendations. But people's tastes vary quite a lot when it comes to the amount of smoke. Because these smokers require so little wood, it takes a little trial and error to dial it in like you said. If those are St. Louis spares, I find I usually end up around 7 hours at 225 with those, but ribs can vary a lot in thickness and meatiness, so I check at 6 hours. I like mine almost to the point of fall off the bone. Others might like a little more chew. You'll find a lot more consistency with your SI than you had with your stick burner, so you'll really be able to fine tune and focus more on the details, like seasonings/rubs, wood species/amount, etc. Have fun!
