Been playing around a lot recently with Imperial builds, in particular Shuttles and Phantoms. A major part of modifying these particular vessels are the Systems Upgrades. As I've been spending more and more time looking at the various combinations I've come to realise that the Systems Upgrades are probably my favourite type of upgrade. I think this is due to my playing 'generics' more than named pilots so I don't often spend much time thinking about Elite Pilot Talents as much (EPT's seem to be discussed a lot more).
So... What is everyone's favourite Systems Upgrade, what ships does it work well with and what 'tactics' does it open up for you in-game?
