I don't understand these kind of questions. What do you meen "best loadout".
That is to me the highest level possible mounted to your ship.
But that is so personnal: Some like a missile launcher, some like two, some dont like missilelaunchers, some like weapons with the same speeds, some don't care, some like as much different types of guns possible, some don't.
You see, you get dozens of answers, wich are all different, but it's up to you to make the choice.
Anyway, since you asked, I don't have types, but I'll tell you what my conditions for a weaponloadout are:
1. Weapons must have the same speed or allmost the same speed. That is because you can aim better with weapons with the same speed.
1. One shieldkiller gun to take down any shield quickly. I used to go for all types of guns, but they never have the same speed.
3. If there are enough gun/missile mounts available, maybe I mount a missilelauncher. I certainly will in the campaign, because you need to destroy all kinds of stuff.
4. the best Thruster/countermeasure/mine
5. The best shield I can get my hands on, no matter wich type. But I usually cary aroud all three types, in case I happen to know who I need to defend mysellf from.
This goes for all ships for me.
Shine my shoes! I want to see myself when I look down on you.
