I believe that Guerra refused to get made;the colombos are the worst family and for sure with 17 rats and the persicos that think to be a mob dinasty , its better to be an associate.
Same think for the bonanno. But ralphie_cifaretto I dont think that a wiseguy will refuse to be made in the Gambinos,in the Luccheses or even in the genoveses that are most stable family.
The Rico risk are nothing with the opportunity to made real money in this 3 families. But is just my opinion.
