WARNING for a new ED players: NEVER and I mean really NEVER fly a ship where you cannot pay its insurance at least two times!
If you will lose your ship, because you have ignored this warning, it's only and only your own mistake! Money can be easily obtained, it is better to do a few more missions or catch a few more criminals, and put a little delay on the use of your new ship than to lose an entire new ship in a second ...
Wanted ask & discuss what you think about using 'A' grade (max allowed size) components vs insurance costs and vs 'gain to ship abilities'. Just noticed that there is 3x price multiplier when coming from B to A and this started me think if for a newbie isn't it contraproductive.
