Personally I like cherry but can't always get it, hickory too but also sometimes hard to get, in Florida oak is always plentiful, like was stated try what you have, try others but like Gary said chicken takes on smoke and flavor pretty quick, remember it is fun to try different rubs, sauces and wood, find the combo you like, one thing I try to do is try one thing different at a time, I try not to change multiple things, this way you know which changes are good for you
