Hyperdrives vs Reactors

[cookie monster]

Under what conditions would two hyperdrives be necessary?

I mean why would one need a fast jump, then the higher hyperspeed kicking in?

It's interesting but for the most part fleets are idle

This combo may be useful when you need both the capability of faster jump initiation (an explorer that needs to run away for example) and faster hyperdrive speed (always useful).
I've played with the idea in the begining but let it go, both for your reason and the fact that I needed the extra space and the advantage this combo gets is not that big. Plus, given the fact that the UI does not handle info about this very well I think it was not intended so it may be an exploit.
