as of now I use Lump charcoal. Brands such as Royal Oak, Cowboy (I know it sucks) and Frontrier. However I don't feel like my coal burns hot enough nor does it burn long enough. I was thiking about switching to using Logs but didn't know if this was a good idea. and if it was what kind of wood should I use? Hickory, or anything that I usually smoke with? Some Oak logs? Does this make a lot of white smoke? Can I lay chunks of the wood I prefer to smoke with on top of the logs? Basically I just want to start using longs cause of the heat factor. Any help would be great thanks.
