KAG, the ribs, for a first-effort, were a success. It won't take you long to get the hang of it. Don't over-think the need for absolute precision to convince you that you need it to cook great Q. While I love the precision of the Auber, I can smoke anything
just as well in my #1 with the stock analog controller.
Here's my 2¢ on your first smoke: Wood is not supposed to smoke the duration of the cook. If it produced smoke for 5 hours of a rib cook, your ribs would be severely over-smoked. You didn't mention how much wood you used. I use about 3-3.5 oz for ribs, and they're plenty smoky. You may not have had enough wood.
Next, you opened the smoker to mess with the cookie sheet, and not sure how many other times. Next time, try to not reinvent the wheel; put your ribs in, with a water pan in the bottom, set your dial to 235. and keep that door closed. Start checking them about 4:45 in, and go another 20-30 min at a time until done. I know you said you've never used a water pan, but it does help.
We've spent the last few years (I'm talking about the whole group, here) trying to find techniques that work best in
our smokers. I'm just recommending that you
try to duplicate what many of us have done with success, and then go from there. If it doesn't work for you, then by all means, modify the techniques to what works best for you. You can produce some stellar Q in your stock smoker, it just takes some practice! Fortunately, this means you'll have to smoke more!
