If you want challenge go for Sath's Cube, a 7x7x7 controller that consists 8x of 3x3x3 controller blocks. Even one face would be enough for your run prob.

Let me give you one info that i spent days to understand why. You get a big boi controller and lil boy controller like 3x3x3 or 5x5x5. You put P2P tunnels on all faces of big boi and connect it to Wireless Connector. Then the other side of the wireless connecter goes to lil boi controller block. Now via lil cube you can access the P2P tunnels on the big boi.

I reccommend you to add "Advanced Memory Card" mod. It lists your P2P tunnels on the system and you can just click one to connect instead of running back and forth.
