There is no reason you can't use a MPD to help retain heat in the stove, and a baro to regulate the draft.

this is ideal^^^, his draft is so strong during times it literally pulls from anyplace it can (hopper, seams, flapper, etc.) during these times the baro would solve this, while he can still use the mpd to hold the heat in the stove (the mpd will not reduce the "suction", the baro will ;) ).

On more nominal/normal drafts im one who believes like you Fred... MPD and the knowledge to know how best to use it during certain seasons, loading, shaking, etc. to achieve the desired effect) ;)

Chris...What I want to know is what is the make up of your chimney ??? It sounds like a real winner and one that most of us can just dream about... I wish I had a strong draft chimney like that which would suck my hat off ! Is yours a masonry chimney ? How tall is it? Does it run along the outside of the house or is it in the center of the house? What is the inside dimensions of the chimney?
Is it terra cotta lined....6"x6" ??, 7"x7" ??, 8"x8" ?? or larger ? I would have no problem throttling down a great chimeny draft like yours.. I Would appreciate your reply description, I am researching the best designed chimney.
Thanks, Ken

It's really just an average masonry chimney I built this past summer. It's an external brick chimney lined with square 8"x8" clay flue tiles. From the point at which the thimble enters the chimney it's about 20' to the top. One factor I can think of would be that the flue tiles are still new and clean and the flue joints are still smooth and tight. Sorry for the sideways picture.
