Ghost which crew?

By TerTer, in X-Wing Squad Lists

So I have a list set, but thinking how to tune the Ghost I'm using.

I started fro this:

"Chopper" (37)
Fire-Control System (2)
Ion Cannon Turret (5)
Hera Syndulla (1)
Ezra Bridger (3)
48pts
But feel Erza is not that great and Chopper ability is used very rare.
Thought of this:
"Chopper" (37)
Fire-Control System (2)
Ion Cannon Turret (5)
Hera Syndulla (1)
Kanan Jarrus (3)
48pts
or maybe even:
Kanan Jarrus (38)
Fire-Control System (2)
Dorsal Turret (3)
Hera Syndulla (1)
Recon Specialist (3)
47pts
Rest of list is:
Poe Dameron (31)
Veteran Instincts (1)
R5-P9 (3)
Autothrusters (2)
Prototype Pilot (17)
Chardaan Refit (-2)
I also tried Dash/Gunner crew instead of Erza, downgrading Ion Turret.
With Gunner i feel, with 4 attack dice, you mostly get 1hit through, so gunner is expensive backup.
Dash i liked, but if you go on asteroids often, you get damage to yourself.
The list in general i like and had good success testing.
What I'm unsure is the second crew on the Ghost.
Hera I want to keep, she's too good and the K-Turns even stressed is great :)
