Help with very defensive formation 3W-2N-3W---2.

[Peter Haralanov]

Hello fellow managers!

I need your help with my main opponent for the League title, our match is in the 25th round.
The last few matches he plays in 3W-2N(DC+DC)-3W---2.


In our first match he played 3W-1-4---2 and I won with Narrow Diamond 2:0.

Anyway, he is 2 points ahead of me and the second match will decide the winner for this season.
His team is currently of about 10% higher quality than mine.

I am considering 3N-1-3W-1-2. What do you guys think?
Or maybe 3-5V-2?

Thanks in advance and good luck with your finals and final rounds!
