If I'm doing pulled chuckies, this is what I do.
Salt, Pepper, Granulated/Powdered Garlic. Wrap in foil and stash in fridge overnight.
Morning, smoke over cherry at ~250 until internal hits 165. Wrap in foil and add 2 Tbsp of Worchestershire. Stick probe through the foil and continue cooking. At this point, you can continue in your smoker, or finish in the oven. When it starts to fork apart (around 195 or higher), take it out and let it rest. When it hits 150 or so resting, pull it and then you can do what you want. Stash in the fridge for later, or top with rub, sauce, for sammies, or whatever.
