I agree again and I think that Cavita mentioned something similar. One thing is to be represented, while being controlled is another. Although the info regarding Giancana being quite mad at Milwaukee's boss and also had one quite heated convo with Balistrieri because he was making deals with Bonanno without Giancanas knowledge, something which gives us another view, meaning I still dont know much about the level of influence Chicago had over these small families. Maybe it was because Chicago placed Balistrieri as boss and thats why the Rockford fam was smarter.

Edit: heres one interesting file regarding Rockford and Chicago...
