Thanks for the input, Locky and Adel. So do you both think I should put no win bonus? I was thinking about putting the minimum bonus, 2M for my level.

I was actually planning a slight variation of the butterfly as below:

---------ST----------
AML--------------AMR
ML---------------MR--
----DMC-----DMC----
-----DC--DC--DC-----

Defence very concentrated in the centre, attacks focused down the flanks. I also prefer to go just attacking, I don't believe in going to extremes anymore. If this formation is okay, I'd rather go with this, agree with your tactics though, Adel.
