After reading the thread by SQWIB about the much sought after TBS, I decided I needed to try chunks. I have always used chips mainly because of the variety I could buy at the stores. But they burn up so fast I was changing them all the time. I happened to have some hickory logs and figured I would try it. After some swinging of the ax and a little sawing I came up with some 2x2x3 chunks. So I put of couple of those in a little metal bucket (coffee can size, also mentioned in the above mentioned thread) and the TBS is awesome. Smoker is setting right at the 240 range and the TBS is just slowly rollin out and has been for a long time. Thanks SQWIB and SMF for all the great info.
