On a Cobra, A4 Shield Generator (125) gives you 33% more shield capacity than A3 (94).
No one mentions the difference in mass and power consumption? These are things that are not so easy to evaluate (how does mass affect agility?). And power consumption for instance is one of the reasons I don't fit shield cells on my Cobra. This power is then missing somewhere else like reducing my options on possible weapons. Or in other words: what does it help if you can last 1/3 longer in a fight if you need 1/3 longer to kill your opponent?
OK, so I need advice. Should I upgrade my Cobra from A3 to A4 Shield Generator? I can afford it.
