In the end Redline shares the same fate like a loaden Rhymer:
He'll be able to shoot once and dies in the same round.
Because there is no imperial Biggs.
Anyway, when it comes to the question about Tie Bomber or Tie Eggbox,
The Eggbox excells in dropping bombs. You can have bombs and mines at the same time! wow - you can even drop FOUR bombs. And Redlines ability does not synergyze - it does just replace Jonus.
So I want to add bombs with Redline because of his high pilot skill, but then together with missiles he would be too expensive.
So in the end I must confess that I dislike Redline because he should have an ability that synergyze with dropping bombs.
