Injector and seasoning for wild hog.

I'm cooking a wild hog this weekend in my roasting box but I wasn't sure which injector to use and which seasoning to use for the skin. I have the Cuban injector and seasoning that ordered from the La Caja China website but I'm still iffy about using it. I thought about injecting with Creole butter and using Tony's on the skin. Any advice would be appreciated. Thanks.
