How should i counter this formation (3w-1-5-1 flat)

@July Fourth Red baron is playing a stronger team which is using 4-2N-3W-1. He is using 4-1-2-1-2 ND as we both agreed upon. He will post his result and so we can see if Narrow Diamond is the correct counter for this as the place is blank on thtable of counter formations.
