It's smart to mix up offences not just use one offence and one defence. Those teams are the easiest to play against because they are predictable.
it's pretty easy to predict an loose against Torööö, even if you know his tactics before the game. And afaik he is running it from the beginning - and you could see that with other extremly succesfull teams, too.
I think in the club is it a solid strategy to concentrate on a main weapon, and make this hard to stop.
Even if i thinking to have a rooster who could play different tactics, is more fun and also could be succesful.
