I'd go with 11 players. If Zara is not carrying the ball you will be able to get a 2D leap blitz on the ballcarrier whenever you want. You have lots of dodge players and I guess he has no tackle. Stay out of contact with the trees. That way he has a choice of blitzing with a guy that can root or one that doesn't get SPP. Even if you are down to 6 players you can still score fairly easily and pressure the ballcarrier. Woodies are far harder for flings to deal with than bash/hybrid teams as the trees are a lot less useful.
