With Crimson Specialist, I'm not sure if Trajectory Simulator is as important. They can already put bombs in weird spots, and perhaps Minefield Mapper would work well. This would free up a point to upgrade those Seismic Charges to Thermal Detonators, and you could start the game with one somewhere nasty. Don't want your opponent flying through the hole in the middle of the asteroid field? Drop a bomb there before starting the game. Hold it from exploding with Nym, and get a real head-start on the zone control. Just something to think about, I can't say it's better per se, but it does something different and pretty cool.

I also think that personally, I might run either Weapons Guidance or Sensor Cluster instead of Advanced Optics (I'd rather have a strong way to spend my focus token, than to keep them between turns. Advanced Optics doesn't exactly open up high-value actions on a B/SF-17 that you wouldn't otherwise have, but I guess it opens up some high-value Red moves).

I'm trying to think of other options for the Sabine Auzituck. It's probably hard to beat, due to raw efficiency.

It's probably risky to fly an Ahsoka Tano with today's PS race, but Captured TIE with Sabine, Thermal Detonators, and Scavenger Crane is pretty nifty.

Fenn Rau with Flight Assist Astromech and VI would also do well as a Sabine Carrier. I think I'd also put on an Ion Bomb.
