I am not filthy, I have a very personal strategy regarding my microbial environment ;p
I am not advocating anything, I mostly stay away from 2-3 and use it very sparsely. I think there is a precise set of circumstances when to use it like FCP and 1-3-1. It's true it's hard to set up an efficient 2-3. In any case, I don't want to have to resort to an extreme defense, that would mean I am desperate and seriously overpowered. It should only become an option on very special cases.
What is certainly a wrong move is to pick 2-3 simply because the opponent attacks inside.
Besides I care A LOT about Clusis manager ;p
