Your opponent's formation is weak through middle due inline position of players. (DMC-MC-AMC). There are few other options. I actually wouldn't suggest Tower and 352 flat, although Counter Formations does, but I'd instead suggest one of these:
3DC-DMC-4-2ST (3n-1-4-2)
4-DMC-2MC-AMC-2ST (narrow diamond)
4-1-3N-2
4-1-4-1
451V
Choose one which suits best to your team.
