I have a KAB5 banjo, and its too big for my 9 gallon kettle, mainly cuz its tall and narrow. If I had a fatter more shallow pot it wouldn't lick flames up the sides.
I can barely get it low enough to not constantly boilover.
But I just scored a keg so a keggle may be in my future. Of course I already bought a smaller burner for the current kettle :|
