3W-5-2 flat Counter?

[Philip L. Willis]

Any suggestion would be greatly appreciated. Lvl 7 Cup Quarter against Lvl 5 league position one team. First game was at Home 1-1 draw, second game coming up, any suggestions, we are very even but my Narrow Diamond is not shining so bright against his 3W-5-2 flat? I will lose possession being away. Yes I don't have a AMR! would get one and play a V, if there was one out there, been looking for 2 days now. NOT happy. Thinking maybe a crazy 3W-2N-2N-2N-1 !! just maybe. up the middle, long ball, own half and Counter....
