Also keep an eye on who you are playing/what their tactics are. I have had some trouble against lower teams who try tons of through balls. Might want a somewhat deeper line for those situations
 
dont mean to sound funny but dont u think i have already tried that?

I've no idea, but given you are claiming .tac files don't work, I can only assume you didn't try it. When I saw your post I did it myself, .tac file in the Tactics folder then look at your archived tactics, the same as before.
