So, since Biggs is only 1 use now, here is a cheaper alternative that is also about 1 use (though could be more than once, too):
Green Squadron Pilot (19)
Draw Their Fire (1)
Chardaan Refit (-2)
Selflessness (1)
A-Wing Test Pilot (0)
Total: 19

If you want, you can add a hull upgrade and that takes it up to 22 points - still 4 points cheaper than Biggs.
It's basically just 19pts that can soak up any uncanceled damage on your main ships. Blank out against 4 dice harpoon? As long as there is 1 or less crits, the A-Wing can take the entire load.
If they prioritize the A-Wing first, that is great. At least they are not shooting your main ships. Also, 3 agi + an evade token each round (and maybe Lowhhrick's reinforce) isn't the easiest thing to shoot at.
This ship probably wouldn't fly well with FSR, but should do a good job protecting other rebel ships (Cpt. Nym, Miranda, Norra, etc.)
