I'm 9-2 now with a 6 ship scum swarm I've been playing off and on lately. It's the first time I've ever run 6 or more ships before, and one of the few times I've run 5 or more.
It consists of:
Palob + Autoblaster Turret + Expert Handling
Syndicate Thug + Autoblaster Turret X 2
Binyare Pirate X 3
Total: 100
I originally had blaster turret on palob for the first many games, but since palob was often the first target, it meant if I had a focus it was often burned on defense, even stolen ones. Now with auto blaster I don't need an action to use it, and the expert handling has let me barrel into range 1 a few times against generics.
Having 3 autoblasters is really nice for any high agility ships that get stuck in the tangled mess of my swarm. Most people go for my z's before the y's since they are easier kills, but that is usually a mistake I've found.
