Welcome, Mike! Congrats on the new smoker! I trust you've seasoned the smoker before your first smoke. One thing you'll find about these smokers is how efficient they are! It takes very little wood to get great smoke flavor. Here's my guidelines (based on chunks, not chips):
Ribs - 2-3 oz
Chicken - 1.5-2 oz
Brisket/pork butt - 5-6 oz.
I weigh my chunks with a cheap digital scale from Harbor Freight - works great! I weighed a hickory dowel (from SI), and actually got .64 oz per inch. Of course, that could vary with wood density.
One other thing about wood: Get good quality wood. The dowels, and the cherry and maple you get from SI are very good. Stay away from "big box" store wood; it's usually older and way too dry (you'll get flames instead of smouldering). For fresh fruit woods, I order from Fruitawood.com. Very good quality and variety, and you can request it in "cookshack cut," which fits in our smoker boxes.
Tell us about yourself in the Introductions section when you can!
