The wood I am burning this year is particularly wet, so perhaps I will 
have something to say on the matter come spring.  That said, my chimney 
has never needed cleaning; I clean the stove pipe, and the basement 
clean out, but the flue has always been clean. I burn almost as hot as 
possible, though at most one fire per day.  I contend that creosote 
buildup comes from burning too cool while in the initial stages of wood 
burning (i.e. before the wood is reduced to coals).  I can imagine 
Reuben being able to burn multiple small fires without creosote buildup 
if they are hot enough.
