looking to replace my VC encore cat with a new Jotul f500 or a Hearthstone (pheonix or bennington). I have had a lot of problems with my VC back puffing and my wife has had enough. I like the size of the stove and love the top loading feature. I am slightly hesitant to get another top-loader because if a new stove back-puffed through the griddle I would go nuts. any experience with either of the three models would be appreciated.
