Bryan B, I like both.
I prefer the lump for hotter cooks, or shorter cooks, with almost no ash buildup. But I like the briquettes from RO too for longer smokes, although you will end up having to empty the ash a few times throughout the smoke, you won't have to add lit coals as often.
It's a trade off. With lump you are always starting a new chimney to keep it at temp you want, but no ash, and a VERY clean burn. I think a person could go 7 to 10 smokes, using lump before really having to empty the ash. Never tried it, as I always empty after I am done. But I only get a cup or two of ash from lump compared to 2 or 3 gallons of ash from briquettes.
Short smokes (under 7 hours) I use lump usually.
Long smokes of 8 to 12+ hours, I usually use briquettes because it's cheaper with less tending, even though I have to empty ash more often.
Don't get bogged down in only using the "best" recommended fuel. Use what you need for the job. I also toss on small 1 to 2 inch dia. dry branches if I only need a little help in temp recovery, or to get enough heat for the last 1/2 hour of cook without having to add charcoal, and then waiting for it to burn out after the cook is done..
Hope this helps you.
