For a single point increase from Ezra, Sabine is flying at pilot skill 5 but also gains an incredible pilot ability. Provided you're not stressed, Sabine has the capability to act like a TIE Striker with built-in Adaptive Ailerons.
The barrel roll is just as useful, and whilst Veteran Instincts would take her to pilot skill 7 making these reactive attacks more threatening, a favourite is certainly Lone Wolf. By the time Sabine is out on her own, chances are the Ghost might be destroyed.
You essentially have a BB-8 built into the pilot, and you can use Push The Limit off the boost or barrel roll action. If you do this, make sure you've dialed in a green manoeuvre, that way you'll shed the stress token gained from using Push The Limit allowing you a third action.
Of course, with Kanan Jarrus on board, white manoeuvres net the same result. If Kyle Katarn is on board, as soon as you shed the stress token, you gain a focus token.
