There are tourny ahead and our main local meta is 2-ship build with 53-pt Dash and 47-pt Horn. And Whisper with some escort also.

My list allows me to effectively fight Whisper and I made some tuning for it against Dash+Horn.

I have two list - optimistic and pessimistic.
Optimistic one has R7 on Biggs, that allows him to last longer.

Blue Squadron Pilot (22)

Roark Garnet (19)
Ion Cannon Turret (5)
Jan Ors (2)
Moldy Crow (3)

Biggs Darklighter (25)
R7 Astromech (2)

Airen Cracken (19)
Swarm Tactics (2)

Total: 99

Pessimistic list based on fact that Biggs and Cracken are first pilots to die and their combined cost in optimistic list is 48 pts. It is 1 pt more than Horn's cost. So I will be defeated if I would kill Horn (and Ion cannon turret makes a lot of troubles for 47-pt Horn) but lose Biggs and Cracken. I am trading R7 for Advanced sensors on B-wing in pessimistic list.

Blue Squadron Pilot (22)
Advanced Sensors (3)

Roark Garnet (19)
Ion Cannon Turret (5)
Jan Ors (2)
Moldy Crow (3)

Biggs Darklighter (25)

Airen Cracken (19)
Swarm Tactics (2)

Total: 100

Which list I should stick? More survivable Biggs or more point-effective with handy AS on B-wing?

What is the "more survivable Biggs" list? I guess that is the idea that you can have Biggs Focus into Evade via Jan and the after Cracken shoots he can give Biggs an action to TL whomever is going to shoot at him. I guess that could work as long as Cracken sticks around with shots to take although shots at ships with movement actions may be difficult to set up.

Part of me also wonders what the Moldy Crow is really doing. I know it can allow you to "save" Focus tokens but that setup may not generate many during your slow rollout. Focus tokens used wouldn't benefit from Jan if anyone thinks that could work.

Yes, Biggs works as you wrote. Gains evade instead focus and gains free TL from Cracken. Sometimes I can't shoot with Cracken and his ability does not work. But Cracken also one of the cheapiest pilots with EPT and take Swarm Tactics for 12 PS turret. There are Green sq pilot that don't have 1 maneuvers aside turns (why it is important - below) and Lt.Blount useless without missle. I will think about him with ion missle maybe.

Moldy crow makes HWK with a lot of focus. I start to move formation slowly along edge and accumulate 4-6 focus tokens before fighting usually. You can then use focus and TL in one turn or use 2-3 focus tokens in one turn (I played with blaster turret before and you virtually can't use it without moldy crow). You can also gain evade tokens with focus action and still have focus tokens.
