I recently had fun trying out this list with a friend:

Poe Dameron (31)

- R5-P9 (3)

Wedge Antilles (29)

- Predator (3)

- BB-8 (2)

Luke SkyWalker (28)

- R2-D2 (4)

=100 pts

My friend fielded a mixed TIE force. BB-8 came in handy a few times helping Wedge to line up his shots. Poe is absolutely all around awesomeness with R5-P9. And Luke was the same old hard to kill Luke. It was nice having two ships regenerating shields during the game.

Incidentally, the last time I tried an all X-Wing list, it was four Rookie Pilots each armed with Proton Torpedoes. I lost that match horribly.

Funny, I was playing around with this almost exact list on Saturday night (I switched out Predator with a few other choices in test matches) and it seems like a surprisingly strong build. I also had fun with a Vader, Fe, 2 x Zeta Squadron TIE/fo squad. Liking the new ships
