Has anyone ever used lump charcoal in the WSM 14.5"? I just got a large BGE which uses nothing but lump and have been getting some great smoke times out of it but miss the smoke rings from my WSM and was wondering if anyone's tried lump in the WSMs to get long clean smokes? When I run standard Kingsford on a long smoke, I'm cleaning out the firebox a few times to keep it burning.
