I've actually been using the 4-5-1 V style to counter the 4-4-2 classic, and its provided me with very good results so far. It's basically total madness tactics and arrows out of the V.
What arrows orders do you use with the 4-4-2 classic? I'm thinking I might give it a try against the 4-5-1 v in a friendly match in a friendly or something.
