FWIW Doug,

My vacpot experience points to chaff as being a major culprit in 
stalls, and I've gotten so paranoid about it that I try to blow the 
chaff out of the grind before loading the vacpot. My real nemesis with 
stalls have been with peaberries, which seem to produce lots of chaff 
(more surface, I suppose). What do you folks with way more experience 
than I have think? And on your advice I will try the finer grind and 
see how that works out.
