you have good aml/amr and you have good dmc.
I would go 4-5-1v, not flat

If one of your wing AM is off for a match, I would go to the more defensive 4-1-4-1 that Nik proposed above.

If you played with 3 DC and oppo attacks from flanks you are screwed.
At least above systems are well balanced, maybe not the best counter for some formations, but certainly never a 100% fail counter formation
