I would also use chunks for your primal cuts & ribs However, I believe pellets, chips & slivers absolutely have a place in SI cooking. Particularly for cold (fish, cheese, spices,etc) or low temp smokes (fish, jerky, etc) or even short duration smokes (2 or 3 hours or less like seafood or stuffed peppers.) With the added surface area these forms will smoke easier and quicker and allow for a more complete burn under those conditions.
