Propane or Charcoal

Charcoal, indirect heat is the way to go. I just did a tri tip today. I have a barrel grill with the smoker/heat box off to the side. I also have a propane fired smoker I use for smoking salmon, a Kingsford kettle grill and a propane grill rounds off the package. The only time I use the propane grill is for ease and convenience.
