If you're brave enough, try this asymmetrical formation, the DCs are to the right, DMC to the left, or even use MR and DMC instead of MC and DMR on the right side of the formation. I think July's formation is better as you'll be attacking down the flanks and DML and DMR will provide more support than DL and DR. You don't want to put blue arrows on that DMR, though, so maybe blue arrows on the right MC so you can put red on the DMR.
