I've only really used squadrons as an after thought, but want to try using these more.

In terms of carriers, I don't have a Quasar, but can field just about anything else - Looking at point costs to squadron values, while retaining some combat capability, VSD1 seems to be the most effective 'carrier'?

But when it comes to building an effective set of squadrons, I'm really struggling. I'd like to use bombers more, with some fighter escorts, but not sure of balance.

Hoping you chaps of an Imperial persuasion could help out this poor storm trooper with decent squadron builds.

Thanks in advance.

How about this...

400/400 Most Wanted , Planetary Ion , Superior Positions
VSD-I, Moff JJ , E-Rax, QBTs, Flight Controllers, Boosted Comms, Grint. 146
GSD-I, Demolisher, ACMs, OE. 77
Gozanti, Vector, Boosted Comms, BCC. 35
Gozanti, Comms Net. 25

3 TIE-B, TIE-A, Tempest, Dengar, Mauler, Sabre, Firespray 117

If you want the full 134 Squadrons you could replace Demolisher with an Arquitens but then you run into problems controlling them so could substitute in more rogues. Even as it stands you may wish to get Demolisher to bank a Nav on turn one then squadron for turn two just to get everything into action.

Yo have 5 bombers to use the BCC well but there are plenty of support units to fight your way clear of strong squadron opposition. Sabre helps deal with Shara and can assassinate Jan from within a bunch of X-Wings especially if Mauler also rams into the pack. Keeping Mauler and Dengar alive gets your bombers free so I included 2 Escorts. Vector by the way is great for throwing in the Firespray or making Mauler speed 5.

Great stuff here ^ if you want to learn how to build squadrons into your lists. there are also some common ideas that I know of like Ciena Ree + Valen, 4 TIEs, Sloane 8, and Rhymer Bombers. let me know if you want more in depth explanation.
