Part of the fun is experimenting! What do you like? My favorite that I've done is a Memphis-style BBQ dry rub on the outside of the skin and a Texas-style homemade BBQ underneath the skin...on the same bird!
I did something like that one year with drawn butter, minced bacon and bacon fat, fresh sage, fresh thyme and fresh basil all muddled into a paste and spread very generously underneath the skin. Topped the skin with bacon and apple slices...turned out pretty good but due to the under-skin stuffing carving the turkey was a little messier.
Williams Sonoma sells a very tasty herbal paste that you put between the skin and the meat. Yum.
