[Cost of R2 on Delta-7B?]

A question came up about the cost of an R2 droid on an Aethersprite with Delta-7B Configuration.  Since the Delta-7B Configuration replaces the agility, does the staggered cost of other upgrades also reflect the lower agility?

Aethersprite with Delta-7B configuration: Does R2 (droid) cost 5 or 8 points?

[Modified TIE/ln Clarification]

Please clarify the modified TIE/ln (scum) Notched stabilizers: While you move you ignore asteroids.

The rules reference FAQ does a good job explaining "ignore obstacles" to include overlapping, moving through and barrel rolling.

Does the modified TIE/ln only ignore the effects of an asteroid if it completely moves through? What if it overlaps the asteroid?  Is there a situation where the modified TIE would take damage from an asteroid? Can the modified TIE/ln barrel roll over or through an asteroid?

Thank you for your time.

[Ved Foslo Ship Card Clarification]

Ved Foslo's ship ability is ambiguous and has caused some disagreement.  There are 2 points of contention.
"While you execute a maneuver, you may execute a maneuver of the same bearing and difficulty at a speed 1 higher or lower instead."
- Can Ved select a 2 turn and change to a 1 turn? (changing to a maneuver not on the dial)
- Can Ved select a 3 bank and change to a 2 bank? (different difficulty)
