Massino do was a powerful and effective don, he took over a family weakened by the Donnie Brasco-case. But he made the Bonnano's a force again. He also respected a lot of the old school rules. he closed a bunch of social clubs and tried to stay out of the spotlight (an example is that he didnt show up for his friend's funeral (John Gotti that is) because he didnt want the attention.

he stayed out of jail for quite a long time, the feds actually hunted him for 7 years with wiretapes and undercover agents. But the problem was that at the end they started to make a case against him a some other family captains. And one by one those captains started to flip.

But still it came as quite a shock that 'the last don' himself became a rat and framed his acting boss 'Vinny gorgeous' Basciano by recording their conversations in prison.
Now the Bonnano's have lost a lot of its power and Massino is to blame for that. But at the height of his reign he was probably the most effective boss.

The most powerful boss is without a doubt the Chin, assisted by his brother Mario and some other old-timers like 'Matty the Horse' Ianniello, 'quiet Dom' Cirillo, Lary Dentico and some others like Johnny Sausages' Barbato, 'Punchy' Iliano or Albert 'kid blast' Gallo.

a lot of those guys got framed in the last months butMario Gigante still survises and in the next couple of years some important guys will be released like Venero' Benny Eggs' Mangano and Gigante's heir Liborio 'Barney Bellomo.

And in 2010 the chin himself will be back.
