I took
Vander with R5K6 and ION
garven with R2 astro
2 rookie X wing pilots
Imperial was..
vader
Howlrunner
backstabber
Obsidian
2 Academy
(no upgrades at all)
I split my force intiially then closed on one side of the Imps focusing firepower. The free target locks and focus cards really helped! I ended up wiping out the TIEs with no loss for the rebels. I'm not a big fan of the Y Wing but I found it's easy to stay out of trouble and use the 360 degree ION to help out the other x Wings.
Left hand side X wings break right and accelerate speed 4 towards right hand TIEs (I think my opponent expected them to do a soft left turn and didn't line up with them well)
