So I am going to do my first smoke this weekend with the new smoker I built and wondered if its worth switching to all wood since I have a nice sized firebox? I have plenty of 2 year old seasoned walnut under my deck with no bark. I also have some cherry and oak. My last smoker (double barrel) always had problems getting a thin blue smoke. Probably because it was poorly designed and built. Mine was always white when I used lump charcoal and some thrown in chunks. Any recommendations on how to keep the think blue smoke on the RF type smokers? Also, any recommendations on how to keep the smoke thin when loading more wood on to the fire after a few hours of burning?
