What formation do you prefer?

Im lvl 9 atm and im using 2 types of formation:

____ST-ST

__ML--MC--MR
______ DMC
__DL--DC-DC--DR


_____ST
__AMC-AMC
_ML--MC--MR
____DMC
_DL--DC--DR

They work well but is there any formation+settings you would like to share or improve my team+settings :)

I like 4-3-2-1 and 3-2-2-2-1 (butterfly)

4-3-2-1 almost as me but with the DMC at the back?

4 defenders, 3 central midfielders, 2 wingers supporting the striker

and how often do you win?, 2 wingers u mean AML and AMR ?
