alphaking, you obviously know your shizznit. don't worry about the lump going out. it will only go out if the top or bottom or both are shut.barring any other freak issues, which do occur. clogging holes (from ash), or the fire dying because huge chunk charcoal doesn't permit the fire to move around like maybe the smaller stuff. at any rate, you are way ahead of the learning curve.first time i did PP, i didn't even know what it should look or taste like. if you mastered that offset, i'd say you will reap the rewards of 'setting and forgetting" the egg.some say you can't really set it and forget it.and some say you can.looks good from here. glad you don't regret the purchase
