I find all this is very interesting, thanks for all the test in the name of bbq.
Now I am thinking that if a person just laced some tender quick in the fire box or even wet a slab of lump or wood with with some TQ slathered on it and let dry, if that would help promote a smoke ring, same as the few lumps of charcoal Thrideye adds. Sounds like a good experiment senerio.
