Hi all, Tomorrow will be my 4th smoke... last time the one 8.5 lb shoulder was eaten in less than 10 minutes, so I need to crank it up a few notches this time. I bought two shoulders totaling 20 lbs and am planning to do them both at the same time in my ECB (one on top rack, one above water pan). So... Does this sound feasible? Should I expect it to take longer to cook two at once than it usually does for one? Will it use up more charcoal or require closer attention during the smoke? Any tips for basting the bottom one? Thanks!
