4 DC? I guess the game does not allow that..
Edit: Ah you probably meant DL DC DC DR
What do you think about 5-2-1-2? So instead of the DMC (which in my opinion ist useless cause my opponent doesn't play with AMC) I will play with a additional DC? Or if I use your suggested formation, maybe I play with the DMC(down)?
DR(up)--DC-DC-DC--DL (up)
