I had an old Charbroil 3 in 1 smoker/grill.It rusted out quick,but ,for me it did the job.I'm buying a bullet type charcoal smoker(Weber or Charbroil 16 or 18" dia.) and want to convert it to propane.I'll use it for mainly grilling.I plan on putting a layer of lava rocks over the burner when grilling.Any ideas on the best burner to use? I've looked at both banjo and pancake style burners.Banjo seems right,but will any drippings from the meat cause issues dripping into the upright holes.The pancake style burners have the holes on the side,making me think the pancake a better option.Any ideas on both burner and size options would be appreciated.Happy Holidays to all!!!
