So something I've been wanting to do is determine what Astromechs work best with unique pilots, I was hoping to brainstorm and come up with a list for each pilot. Once more salvaged astromechs and scum ships that can take them are released I'll do something similar for them. I'll start off with my ideas:
Tarn: R7, always R7 their synergy is supreme and makes for a cheap and effective ship choice
Luke: R2-D2, Luke is a defensive pilot and R2-D2 boosts this and helps increase his survivability
Biggs: R2-D2, R4-D6, R5-D8, R5-P9, R5 any sort of damage mitigation can help increase Biggs' usefulness and keep him alive longer to be effective.
Wedge: R2-F2 (this would prolly work even better with EI), R7-T1
Hobbie: R5-K6, R7, R7-T1
Garven: R5-P9, R2-D6 (with deadeye or calculation, even better used alongside the moldy crow, especially Kyle)
Corran: R2-D2, R2-F2
Dutch: R2, R7, R7-T1, R5-K6, R5
Horton: R2, R7, R5
Wes: R3-A2
