I have a webber, so probs diff, but trim it, rub it, put it on a bed of fresh parsley, let it smoke until it hits 170-180 internal temp, wrap it, then smoke it until you get it around 210 internal temp and your thermometer slides in like there is nothing inside the foil. Pull it, still in foil, and stick it in the fridge for 30-60min before cutting it.
I use jack stack's rub and it works great.
Ppl will say that wrapping it is cheating. eff that, as long as it is delish, who cares.
