So I've been running this list currently:

Onyx Squadron Pilot - 39 points

HLC

Wampa - 17 points

stealth device

Youngster - 18 points

marksmanship

Colzet - 26 points

proton rockets

tie/x1

fire control system

It comes in at 100 points even. I've only flown it four times went 3-1 with the loss coming to a swarm. The defender being at pilot skill 3 helps against most tlt lists since those are at two, and because of the named pilots and their abilities in the squad tends to be overlooked until those 4 reds start chipping away at ships. But after flying against and seeing how well Omega leader can be I'm thinking about switching Colzet out. Omega would be the typical build so

Omega Leader - 26 points

Juke

Comm Relay

While I feel that Colzet works well with Wampa's ability, and like the idea of possibly dealing direct hit to say Corran Horn without ever touching his shields I don't know if Omega Leaders ability might be more viable over the course of a game. I saw him burn down a Soontir Fel easily because Fel couldn't modify anything making at least his focus token worthless. Throughout the game he just seemed to be a general pain to deal with. I'm looking to practice with it a few times this week with Omega leader at open play, but plan on taking some version of this list to a store championship on Saturday. So any thoughts on what is the better ship between the two?

I love both. That being said Omega Leader can pull some crazy ... out of his rear. Tie/fo has such a good dial it is unreal.

Omega Leader is more dependable and has an effect that is really strong in this meta, I'd say go for him.

I used Colzet in several games of late, paired up with Vader and generic TIEs. Even though I failed miserably overall, Colzet was still doing some work. His ability did not trigger too often, but when it did it worked very nicely adding some negative effects to enemy ships. I was running him very cheap - X1 Title and Fire Control Systems only, usually going for Evade action. Little bugger was always a concern to my opponents. Unfortunately, by himself he does not have the damage output to be a "hammer" of any sorts...
