Hope you enjoy your SM066. I've had mine for about 7.5 years and I love it. Not sure if you were asking a question about wood, but I never use more than 4 oz., even for long cooks like brisket or pork butt. For things like ribs, chuckies, or pastrami, more like 2.5 - 3 oz., and fish maybe 1.5 oz. I have some almonds in right now, with 1 oz. of hickory. And of course you should use chunks, not chips, and not soak them. Enjoy!
