I don´t have six copies of Crack shot, so let´s get that out of the way!
I figure you have to be able to deal with Crack Shot swarm, maybe a rebel swarm while giving yourself some sort of late game chance against aces.
So, here is what I came up with:
Howlrunner/Crack Shot
Omega Leader/Comm Relay/Juke
Dark Curse
3x Obsidian Squadron
What I like about it is that you get 3 shots off against a Crack Shot Swarm since three of mine are PS6 or higher, and the whole swarm gets to shoot against a rebel swarm with a lot of PS2. Then you have Omega Leader and Dark Curse which have a lot of staying power and can be annoying late-game. Sure, Omega Leader is only PS8, but getting the highest PS is really tricky these days because you can face a PS11 Vader and a lot of PS10s with an initiative bid.
I really like the idea of Omega Leader in a swarm because he is cheap enough to make a 6 tie swarm with Howlrunner and it´s really iffy to target him early because of Comm Relay. He´s also really strong with that Howlrunner reroll, pilot ability and Juke.
In any case, this is the first time I have been excited about a tie swarm in a long while. What do you think?
