I'm a new egghead, just got my L BGE this year and I'm cooking all the time. I've used different lump charcoal in addition to BGE Lump Charcoal, and the best I've found so far is Rockwood Charcoal. I've found it to have high heat content, long burn times and little ash. There is little smoke when cooking. The results have been superb.
What I've cooked with it in the last week: Chicken breasts, chicken strips, pork tenderloin medallions, focaccia bread, pizzas (5), hamburgers and ribs.
Good size lumps throughout and none of those small little marbles that stop up the holes in the fire bowl. I will be buying another bag.
I found it at Bluegrass Grills in Versailles, KY.
