Thanks for the ideas Vince B.
I'm using Chris Lilly's dry rub and injection. I will see how it all turns out tomorrow.
I'll get a feel for things tomorrow though, it's sitting there waiting in the fridge til morning.
I decided to trim a lot more of the fat than I originally expected. I feel like the rub would get into the meat a lot easier that way.
This is how they look right now. Wish me luck!
