I find Jek Porkins works well with R3-A2. What astromech is best suited for Wedge, Wes, Luke, Garven, Hobbie, Biggs and Tarn?

Tarn is good with M9-G8 or R7

Biggs is still good with R4-D6

Hobbie loves Targeting Astromech

Garven can use R2-D6 to get VI

Luke still wants his R2-D2

Wes also meshes well with R3-A2, as he strips a token and then requires a predictable green. FAA is also nice to try to ensure you get arc.

Wedge is probably best with FAA or BB-8

Can't wait to try BB-8 with Kullbee.

Aside from that, FAA is pretty much a go-to for most, except R2-D2 with Luke.

Hobbie and Targeting Astromech is pretty great, as @Mrk1984 pointed out.

Tarn and M9, yes.

Hobbie and Targeting Astro, yes.

Garven only needs D6 and VI if he isn't the highest PS, and higher PS friends are not his kind of friends anyway.

I like Biggs with D6 so he can get DTF or Selflessness.

Everybody else EXCELLS with FAA. It is a very rare day I find that isn't the best choice.
