Most folks will tell you, and I'd agree, that any benefits of the smoke via wood was done in the first hour or two of the cook. As for the pull temp, temp is helpful but shouldn't be your final decision maker. Pull the meat when your probe, or a fork, or a knife, or anything with a sharp edge goes in like it is butter. Sometimes that 195, sometimes, 200, sometimes something else, but it's always when the fats and things in the meat have melted away and are no longer holding the meat together.
