I'm thinking about taking this list to my Store Championship this sunday, any suggestions on improvments?

Store Champ? (199)
Cutlass Squadron Pilot — TIE Punisher 36
Trajectory Simulator 3
Skilled Bombardier 2
Proximity Mines 6
Proton Bombs 5
Ship Total: 52

Soontir Fel — TIE Interceptor 52
Predator 2
Ship Total: 54

Darth Vader — TIE Advanced 70
Supernatural Reflexes 12
Fire-Control System 3
Afterburners 8
Ship Total: 93

Get rid of Afterburners or Proximity Mines for your bid.

You need to control initiative with those aces.

Prox mines. Get rid of prox mines for the bid. In fact, I would go Soontir with Predator, Vader with FCS, SupRef, Cutlass with TrajSim, Proton Bombs, Barrage Rockets, as your basis. 11 points left for an upgrade or two/a bid. The Rockets give the Cutlass something more to do.

Thanks for the input. I've removed the Prox Mines and Afterburners and added Barrage rockets.
