[FT] Question about Drives

I've got a couple of questions about Main Drive systems that I've been
pondering...

First, how much more would a drive system that did _not_ have the
rear-arc firing restriction be worth?
In cinematic?
In Vector (if you keep that restriction in vector)?
For either standard or advanced drives.

Second, consider a game with both cinematic and vector thrust (for
instance, in the EFSB, only the Minbari used Cinematic movement), how
much should the cost of the cinematic drives cost compared to the vector
thrust ones?
Assume the following special rules:
Cinematic drives, while in use, prohibit fire through rear arc.
Vector drives do not.
When determining missile lock-ons, the lock on range is 6mu vs.
cinematic, and 3mu vs. vector, if there is a choice in targets, double
the range to the vector targets.
Plasma bolts have a area of effect with a 4.5mu radius (as a
compromise).
Both the cinematic and vector drives come in both standard and advanced
forms.

Just some ideas I've vaguely been thinking about for scenarios, etc.
