What Light Squads are you using for Light Side 9A and 9B?

I borrow either GK or Wedge (I have both, but their combined leadership is necessary for this lineup). Run GK, Wedge, Biggs, OG Han, Baze and Ahsoka. The sheer amount of burst damage coming from Wiggs and/or GK/Ahsoka, combined with OG Han to stun B2 before he AOE's and Baze to absorb damage will allow you to 3-star any of the LS 9-x hard battles.
