They all didnt flip...

Tommy Reynolds and Fabritz... Took it on the chin.
They were both feared killers in the neighborhood, they were respected for the work they did for the crew (MURDERS)

They were all tough guys when they were all together
There were 7 main guys and 50 more wannabee's

So when you would fight them they would all stick together

Also, they had the Bonanno family behind them Tommy Karate who was a killer, Spero was an old time BOSS.

The only way you could go up against them was if you were part of a crew that also had murderers

They went up against BPB, and that didn't go too good for them.

I know they went up against the Ft. Hamilton Crew and one of them had gotten beaten to death, Ft. Hamilton was another Colombo farm team from bensonhurst, Wild Bill was behind.
They got into a beef at a club and Ft. Hamilton Beat one of the Bath Ave Boys to death. I dont want to say his name out of respect for his family.
