I use light smoke when combining cultural flavors with smoke. As an example, a light smokey flavor merged with the predominant flavors of Italian cusine works very well. However, it can be used to add depth of flavor to almost anything. The key is to make sure its light enough to not obscure or muddle the original flavors.
Also, one of my most common cooks is to par smoke a chicken for 2 hours @ 225 or a butt for 3 or 4 hours, then put in a Dutch oven and braise with onions, garlic & (chicken stock for the chicken) & or white wine until the protein is falling apart. Great by itself or on tacos, or as the base for a soup, or pot pie or shepherds pie, etc.
