I think 11 is my favorite base personnel. Now I keep going back and forth on which I like better between 20 or 12. I think it really comes back to what you have as far as players, but all things equal I don't know which route I would rather go.
I like 12 better than 20. For me, again it was back to some sets that I think are more difficult to align than prepping for another insert player/gap or for that matter. TEs are your friend, especially vs Odd fronts in my experience.
My favorites are these - 11 Personnel
