That said, I think that the right one is a little too "blowtorch-y" for me. As Smokey said, too much air just sends a lot of the heat right up the exhaust. If you can dial the air back a little bit, I think you'd be right on the money.

If you are getting higher exhaust temperatures with the same feed rate, aren't you generating a hotter stove and theirfore getting better heat transfer?
Has anyone checked their exhaust temperature to see what's ideal?
I would venture to guess that at some point the incoming air mass (if greater than what is necessary for good combustion) begins to generate colder stove temps but has anyone taken flu readings to see if this sort of situation can even be generated in most stoves?

Actually a higher exhaust temperature at the same feed means the heat is going up the flue and not being transfered to the room air via the convection system.
You want the exhaust temperature to be just as close to the condensation temperature of the byproducts of combustion as you can get it and still have the byproducts exit the flue. If your system can actually deal with the condensing byproducts you want the flue temperature so low everything condenses. Burning wood that means the tars, and other really nasty things.

Question, what are the temperatures of the exhaust gases, not external stove pipe temperature, exiting the chimney flue/pipe outside on your stoves? I checked mine the other day and it was around 330 degrees F on the medium low burn setting. I didn't check it on the higher settings. I am not sure if this is the normal exhaust temperature on these pellet stoves or if the length of the stoves exhaust piping has any effect on this temperature. Mine is straight up, no 45s or 90s, the existing masonry chimney flue using a flexible AL29-4C stainless steel 3 inch pipe around 14 feet long. The stove was run about a week since the last cleaning when this temperature was taken. I could hold my hand over the pipes exit for a second or 2 but that was about it.
