I wanted to build a list for Wedge and give him Expose, and minimize the draw backs. This is first take on the list, and I think this will be a fun list to play.
Wedge (29) + R2-D2 (4) + Epose (4) + Shield Upgrade (4) 41pts
Biggs (25) + R2-F2 (3) + Stealth Device (3) 31pts
Dutch (23) + Ion Cannon (5) 28pts
Biggs draws fire, and protects Wedge from the -1 defense, and with 4 agility he's going to last a lot longer. Dutch gives Wedge a Target Lock which will make Wedge that much nastier. I gave Wedge an Extra shield and R2-D2 to help keep him around after Biggs Falls. With this list Wedge should be hitting even the hardest targets, and making that much easier for Biggs or Dutch to finish off.
