Hey all - I've had the CG smokin pro with sfb for about 2 months now and I've had trouble maintaining temp. Today I put the grill grates in the sfb and put the coals on the grate. I also put some foil around the lid to keep the smoke/heat from escaping. It seems to be working. I've kept a constant heat today of 225 for about 2 hours now (i'm doing a couple small pork shoulders - about 2.5 lbs each). Anybody else put the coals on the sfb grate? Is this a bad idea? I'm new at this so I'd appreciate any advice.
