Tilted

You have a fair amount of anti-ship firepower, I'm just mildly concerned about the thin-ish squadron cover given that you don't have activation advantage. If you're just going to have fun, it's probably more than enough. THough I have to ask either way, why is Vader not on the ISD?

There's a fair bit of points I could cut, Motti over Vader for example, that would get a good handful of cheap squadrons in there.

Black Squad does not really have anything to protect and does not have swarm, Sabre is an Interceptor without counter. The one snipe attack will propably not save you anyway.

You only need three more points to get Howlrunner+3 TIEs, who can hit pretty hard for a meager 40 point investment...

You don't really need Boosted comms for the fighters who won't last that long and shouldn't be straying too far from your ships.

I would give the first VSD GTs and take the other VSD down to a VSD1 with BTs and Ext Racks. This might free up enough points to upgrade black squadron to Zertek or Tempest for a bit more fighter resilience.

Vader is probably safer on the ECM protected VSD

I could see myself running something similar to your list maybe something like this...
