It is always good to have another options.
I usually use variations of 451, 361 and 352. I don't have own style because I set my formation according to opponent too.
I'd like to use 3x3+1 more often but strong mildfields doesn't allow me that...

I wanted today to suprise my opp with 3x3+1 but he has 3mc+dmc+amc, so I have to use other formations...
