Flew this list yesterday:

Dengar (51)
JumpMaster 5000 (33), Attanni Mindlink (1), Unhinged Astromech (1), Punishing One (12), Engine Upgrade (4)

Boba Fett (49)
Firespray-31 (39), Attanni Mindlink (1), “Mangler” Cannon (4), Greedo (1), Engine Upgrade (4)

A lot of fun especially with the mindlink. ML gave me a lot of flexibility to boost with one whilst the other generated focus for both. My instances of stress were largely mitigated with Dengar's astromech being able to clear stress on 3's and give a focus to a stressed Firespray. I wasn't able to make great use of Dengar's pilot ability given that he was generally being chased by Tie's while Boba routed from the rear.

I will likely try this list next time, swapping for Tel and trying out Dengar as crew:

Tel Trevura (49)
JumpMaster 5000 (30), Attanni Mindlink (1), “Gonk” (2), Unhinged Astromech (1), Punishing One (12), Hull Upgrade (3)

Boba Fett (51)
Firespray-31 (39), Attanni Mindlink (1), “Mangler” Cannon (4), Dengar (3), Engine Upgrade (4)

My version:

If Dengar misses, you can activate Bossk and get a focus+tl, stress if you didn't already. Boba thru mindlink gets a focus and stress as well. This frees Boba up for a boost or some other action than focus. Dengar has a focus+tl for his second shot against his attacker and on the next Round Boba gets a tl when removing stress.
