K2, that chop looks perfect!!! Slightly pink, and oozing with natural juices from the cut. Gotta love it!!!
You will find that lump does burn much hotter than briquettes, so fire control is even more critical. If using the minion method, placement and amount of hot coals, as well as reserve fuel, may take some experimenting to get a happy medium of moderate heat and continuous long burn time, when needed. You might find that using a dozen or less hot briquettes to get your lump started will be easier to judge than tossing a couple chunks of hardwood lump into the chimney and hoping it's the right amount. For shorter smokes like your chops, you can definitely use much less reserve fuel. You'll nail it down better with each successive smoke...smoke and learn, and, most importantly, enjoy the resulting eats!!!
