So the more I think about it, the more I think Afterburners, unless extremely expensive, will be close to autoinclude on most highish Init ships. Even if you have boost already, the ability to pull a free boost and still have an action is so huge.
Wedge gets double repositioning for a turn, as does Vader. Fel gets to burn into a Boost, Evade for action, link into a roll, then get a Focus if he's got a target in arc. Fenn could boost into R1, then roll and link into a Focus. It's not every turn sorts of action efficiency, but on key turns, you really get to get the most put of a fighter.
