I'm from Brazil too, and what I can say is that Sao Paulo and Rio de Janeiro have awesome players... but I'm from Belo Horizonte and there have few players, and among them, only a minority wants to training and develop some skills (nothing more then 4 players). I tried to convince them to play more accurate, but without success...
About the combos, I think they are pretty good, and I'll try to participate in the next.
