Why not try it out now, low cost 1st try would be chicken leg quarters,
1. brine [soak in salt water or seasoned water] at least 1 hr. over night is better I use a powdered crab boil mix
2. WOOD, every wood gives off a different taste and that is subjective to your tastes, Hickory a little sweet, Misquite , a little earthly , like is said it's subjective. soak some of the wood over night,when the coals are ready wrap the water soaked wood in tin foil, add that to the coals plus a hand full of dry chips , add meat, cover , sit back and enjoy life, leg quarters should take about 3 hrs.
