Howbout a unique that adds a hit result to the roll whenever you spend a target lock? Wording would have to be something like "When you spend a blue target lock to make an attack, or spend a target lock to reroll dice, add one <hit> result to the roll.
Of course it'd have to be fairly expensive, cause it has uses after ordinance is spent.
Howbout a 2 pointer that lets you stress yourself to add an evade result to your defense roll, provided you aren't already stressed? Better elusiveness that doesn't require an EPT. I'd take this with, well lotsa stuff, but it strikes me as a good way to make rookie pilots meaner. Or I guess to have a super tanky Ywing.
