moister from the self basting
I always brine mine first... no worries after that ...
as for the OP's question... I also only do a breast (brined) in my Mini ...
For crisp skin you have to dry the skin.Put it in the fridge uncovered over night or use a fan for ~3hrs -either method until the skin is dry or really tacky to the touch....One of those folding Geisha fans or a palm leaf works good for fanning....HAH! o_OI brined and smoked a small turkey once. It looked like it deserved to be on a box of stove top stuffing or something. Looked perfect. If I tied off the legs and pumped it full of air, we could have shot hoops with it because the skin was so rubbery. The meat was moist and tasted great though. Skin was not edible.
