Humm. 4-4-1-1 is one of my favs. Its my defensive version of 4-2-3W-1 hehe.
By the defensive side, 4-2-3W-1, 4-4-2 and 4-4-1-1 are weaker through the middle and stronger through flanks. So IMO, that's where you have to try. Maybe a 41212 or some variation of it. It has been a long time I dont face this formation, but old times I used to counter it with 3N-4-1-2 through the middle.
