I have a pitmaster iq110 that I use w/my 18.5 wsm. I set it up for minion method using kbb mixed with wood chunks. to do this, I fill the charcoal ring with the kbb and chunks, then remove the briquettes and chunks from the middle and put them in a chimney starter. then I fire up the chimney. when it(the chimey of kbb and wood) looks ready, I plug the iq110 in and plug in the power and thermocouple wires and set it for my desired temp. next, I dump the chimney into the void I created in the charcoal ring. once that is done, I assemble the cooker(instead of water in the bowl, I use foil balls and foil to cover the water bowl) with the thermocouple at top grate level and wait for it to come up to the set temperature. when the temp is holding steady, I remove the dome and toss on the meat and then replace the dome. then I let the magic happen.
