As you await your new smoker, your best investment will be to read this forum. There is so much advice on here about any topic you want to know. But one thing that I have seen become a failure for too many users who migrated from other smokers is using too much wood. And it will be bitter. Get a kitchen scale and weigh your wood. You only need between 2 and 6 oz for most smokes. These smokers are efficient! Download the Guide to Smoking Times, Temps, Woods from here:
