After 15-20 smokes on a hand-me down ECB, I went to the local hardware store and ordered a WSM 22.5". It will be here on Friday. I'm going to have a limited amount of time on Sunday and wanted to do a short to medium length smoke (less than 6 hours). Ribs or maybe a couple of chickens... I don't know, depends on what jumps out at me when I go to Sam's Club. From what I've seen here it seems like most who post here use Lump charcoal in there WSM's. Is that still the case? Also for a 6 hour (or less) smoke, should I fill it with charcoal completely (and close the vents when done) or only fill it partially?? Thanks for any advice. JP.
