I am currently using a Charbroil H20 verticle smoker. When I smoked a rack of ribs this past weekend, I tried to fill the tray with unlit lump and poured a hot chimney of lump over it to keep the fire going nice and steady without reloading. I had to do 2 more chimney fulls during the smoke (keep in mind this was no marathon smoke, just a 2-2-1). Any tips out there on keeping that fire going without reloading too often, i.e. minion method? The lump doesn't get much ariflow the way this thing is designed, but that can't be my only problem. I'm not sure the poundage on the bag I used, but I went through about 3/4 of a relatively larger bag, 10# maybe??? That seems like way too much to me, but maybe I am wrong.
