i think 4-1-2-2-1 is better but i suggest you to try: 4-1-2-3

Every formation also can be beaten...
It all depend on your players quality...
4-51v could be demolished by 3N-4-1-2 as well ..but vice versa...
4-4-2c mostly dead with 3-5-2 flat or ND or even 4-5-1V but they all so can beat tem if you are stronger and right strategy...
