Just my thoughts but Gravano was just a little bit more shrewd and always knew he could broker a deal with the Feds after he was pinched. He was able to play Tough Guy when he was free and walking around , and always knew he would be able to RAT if and when he was not able to beat the charges. I don't believe that he was ever a tough guy period ! For Christsakes he was a Friggin Hairstylist before he was made.

wise old owl sat on a oak , the more he heard the less he spoke , the less he spoke the more he heard , wasn't that a wise ole bird.
