Casso would probably be my first choice. The guy was a huge earner and seemed to have his hands in so many things. He was on good terms and did work with high ranking members of other families like Frank DeCicco, Greg Scarpa, and even got to meet the Chin a few times. I also find him running the family while being on the FBI's most wanted for over two years to be fascinating. His time at the top was during a very volatie time during the history of the mafia.

Greg Scarpa Sr would be another one. He was another nut job, and he also worked for the FBI on big cases like the Civil Rights case in Mississippi. He had to have a lot of interesting stories.

There are other guys out there too, I just have to think about it for a while.
