Which ship for each system?

The other night Ukiller, the new admiral of my clan The Ghost Warriors, was helping me to clear a white tech hunting mission. I'd tried 'Swipe Advance Protector' on Prosperous several times but just couldn't get the Custodian Commanders to drop a Blue Print (BP).

I'd convinced myself that the mission was bugged and even raised a ticket. The response was quick but just said that one of the SGMs, Rainion, had tried and completed it, so the mission was okay. Luckily the next time I logged on, Ukiller was on Prosperous and came to my aid. He killed the escorts while I blasted the Commanders, so that the drop chance was based on my tech level not his. It still took forever just to get the two BPs I needed.

While we were there the boss (Ukiller) must have checked my profile and ships. Seeing that I had a brand new Mizar tank, the MST-FF2 Fusion Armour, he advised me that I should swap it for a Storm. Apparently I'll have more need of firepower than armour in Mizar. He then went on to explain that all systems had X ships, and that you should get the same class of ship as the X type. The Mizar system has a MST-X Fusion Storm so you should get a Storm.

Very interesting. I've almost finished with Gemini, whose X ship is a GC-X Fusion Engineer, so according to Ukiller's coaching that should have been the ship to go with. Now it just so happens that I started Gemini with a Storm, but later on got myself an Engineer as many of the missions involve protecting other ships.

So if the theory is true, you should have a Shock in Antares, an Engineer in Gemini, and a Storm in Mizar. Vega has an X Storm, Tank and Shock so just make sure you don't pick an Engineer. In Sol the only X is the Sniper and in Draconis the Defender so presumably you should be okay with any class, or at least equally handicapped.

So I think I'll take my boss's advice and get another Storm for Mizar, which will help with white missions anyway. The Tank in my hangar will probably get armoured up and equipped eventually. I've a lot of grinding to do.

Now don't go scrapping half your fleet just on the basis of this post. While I would not dream of doubting my Admiral's counsel, I've got through Antares in a Storm so it's obviously possible to go against this advice and succeed.

Update
Disagreement already on which ship to go for, I love a healthy debate/good argument. I've just added a poll to the site (top right) so you can have your own say. I reserve the right to ignore the results completely and do what ever the hell I want.
