Hmm. You did not check well I think. If you go on page 1 of the "Table of counter formations" thread 4-5-1 V is suggested. I always used this and won 100% of the times. On page 61, t_11 fan suggests this: 3N-1-4-2, 3N-5-2V, 3N-1-3MC-2WAM-1, 3N-1-5-1. Never tried but I know that 3N-1-3MC-2WAM-1 is deadly against 4-3-3.
