I would use a smoke tube with wood chips in the chamber to get added or "unprocessed" smoke flavor over running chips with pellets through the auger. I have the bigger LSG pellet grill. It probably will feed, as they say. But the burn pots burn hotter and cleaner. So you'll get less smoke than a smoldering smoke tube would generate. And I concur with the long cook strategy for best effect. Shorter/hotter cooks probably won't benefit much. Yep, I think you would get better effect and burn less wood chips in a smoke tube. I think the pellet mix-approach is a bit gimmicky.
