Strongest team at my level plays a 4-3w-1-2, League title on the line, what to do?

3n-3w-2n-1-1 as motrin said, or 5-2n-2w-1. That's my favourite. You may even go extreme and remove the ST for a DMC. Hard defending.
I always used 4-5-1V, since it goes along well with ANY tactic which is not attacking. You may put down arrows on DMC and the MCs, play hard defending and pass mixed and short — when you have the ball, the game is the safest even if you have a 9* defence.
It's hard to win like this, but easy to lose otherwise.
