Quickdraw shoots first and sets up a Target Lock for the other two ships:

1) Vessery can use QD's TL for his ability.

2) Karsabi does the same thing, but it's a little trickier.

- Karsabi can do ANY other action beside TL. Focus for defense is preferable, but if he needs to SLAM or RELOAD then he can discard the Weapons Disabled token and take a stress. On his turn he uses QD's TL to fire a Concussion. I chose Concussion because it has double mods built-in with GC, and keeping the TL is not important. The only thing I think I would change about this list is MAYBE use Wired instead of VI on Karsabi. VI gives him a little more independence if it is needed though.

This squad is Fenn Rau proof in many ways.

I would strongly support Wired rather than VI. Other than that, the builds themselves seem solid.

Now, my beef is that I like to build each of those pilots heavier, but for fitting them all it, this seems nice. I could, however, see ASTS on Vessery being really strong, as it provides Fenn and stress proof dice mods. You could put that on QD as well, though VI could be good there as well.
