I have a Pro 780 and have used it a couple of times so far. The first time I didn't notice any smoke coming from the grill so this time I watched it closely while cooking a brisket. I used the same Traeger brand pellets I always used in my old grill and cooked the brisket at 250 degrees. In nine hours not one puff of smoke. The brisket was good, even had a smoke ring?? Is this the new technology?
