Warsmokeeagle, if you do decide on some chicken breasts, go bone in and brine the night before or at least 4 hours before they hit the pit. The white meat will have a tendency to dry out while smoking, a brine, a simple mixture of water with equal parts sugar, kosher salt and your choice of spices and herbs will not only help keep moisture in the meat, but also infuse other flavors as well. I like my chicken spicy, so I add cayenne and some of my chicken rub to the brine, combined with the salt, it really gives it a kick, but not so spicy that it can't be eaten by those not liking hot food.
My brine:
2 quarts water
1 cup kosher salt (if you don't like a salty taste, cut this down to 1/2 cup)
1 cup sugar (brown or white, if you cut the salt down, cut the sugar down to match as well)
1 TBSP cayenne
1 TBSP chicken rub (or whatever you like on birds)
1 TBSP minced onion
Make sure you have separated the skin from the meat a little so that the brine can get in between the two and really surround the meat.
About 30 minutes before hitting the smoker, pull the meat out of the brine, rinse off with cold water, season both sides and off to the smoker. You can also soften some butter and mix in your rub then put a heaping serving of the butter / rub mix under the skin on the meat.
