After failing to find a layout that has all resources behind walls, I decided to make my own. I barely made and started using this at the same time, so I don't know yet how it will do against attackers, but you should check out the heatmaps and see that EVERYTHING (except TH) is protected. Useless buildings go outside of the walls; Defenses and ALL resources go inside, with slightly more protection for dark elixir storage. No matter what direction you are attacked from, they will have to break through two layers of walls to reach any of the gold/elixir storages. Archer towers protect their own box the small center boxes on both sides, Cannons protect their own box, and wizard towers protect the center boxes plus halfway in the side boxes, Air defense placement pretty much covers most of the base, and finally mortars provide splash damage for everything two of the mortars can protect the dark elixir. It's strategically a great base since all defenses protect each other, but again, I don't know how well it stands up in defenses yet.
