Don't forget the poor X-wing, who has to give up Integrated Astromech to take this. Which is not going to happen.
XWing title: equip two modifications.
Then you could have your IA and GC!
XWing title two: enhanced engines - gain a green hard one and a boost. 2 point upgrade, T-65 only.
Here's what I'm thinking: Rebel operatives who stole the Death Star plans also stole the plans for the Tie Advanced Prototype. The plans were then incorporated into a prototype T-65 ship. (Vader was pissed when he discovered the plans for his beautiful ship were stolen, and he had to fly around crappier ship!)
If the X-Wing gets any kind of help with torps it will very likely be in the form of an ordinance-specific astromech, or with a title that gives it some kind of TL-trickery. Thy will not get the Royal Guard title
