Doing my first turkey as well. I have a 20 pound bird in the brine right now. I'll probably do some rosemary butter under the skin, and do a vertical roast with a little apple wood for smoke.
Fingers crossed... :)
I make sure I have a lot of corn meal under the crust on the peel- it slides off the peel onto the stone with no problems. Comes up nice and clean too. All I ever have to do is brush the stone off and its good as new.
