i always having problem when facing 4-5-1 flat opponent with about equal strength, either draw or loose.

i have tried 4-5-1 V-style and 4-2(MC)-3-1, but seems not work well,

i plan to use 3-5-2 V-style which i never try before, but it kind of headache either to set my Defender 3W or 3N,

anyone can help me?

or any better formation?
