i play a 3.1.4.2 formation and my team play attacking football

i was wondering if it is a good formation to have for an attacking team or will i allways come up short in the title race.because i play no full backs i am thinking of taking out the dm an putting in an attcking mid which would make the formation 3.4.1.2.

It might work at home but you can't play it every game. I play 4.2.2.2 all out attack with 2 CMs and 2 wingers against weaker teams and thrash them every time at home, but no way would I play it away from home.
