Lots of good advice here. I also found lightweight weapons lacked enough punch. The Courier is already firepower-challenged, and lightweighting the weapons drops it below acceptable levels, for me. So when I was building my Courier I found it was ludicrously fast to start, but the speed fell as I modified it to be useful and survivable in combat. That meant full-weight beams and I added a HRP for integrity, and speed fell drastically. In the end it was not as fast as I had hoped, but it's balanced in my eyes. A ship this fast is not in much peril from AI boats when flown well. The real threat to a fast Courier is collision, so I felt integrity was crucial.
I also ran through an enormous combination of weaponry before finally coming full circle and mounting two beams and a corrosive MC. This ship was a special project. My intention when building it was a ship that would be flown flat-out, full time. A ship that makes gunnery passes, and doesn't saddle up. Wide open, slashing attacks against fleeting targets to get tags. If I kill it that's great, but the idea is a ship that extends from the furball at speed, then carves a big arc to make another high speed attack, not unlike a Focke Wulf 190 making passes against a stream of B-17s, ya know?
And because of this I found many weapons were not suitable, like frags, which, while devastating, are ill-suited to such closure rates. Same with rails and any fixed weapon. The beams and MC combo work well enough, but with fall-off the effective window is fairly narrow. But tags are what I am looking for, not kills start to finish. I have other ships that do that.
And it is a lot of fun flying combat like this. G-loc is common, and the thrill of these types of attacks as you navigate at very high speed through a target-rich environment never gets old. I did lose it one time in a collision with a NPC named Andrew Knox. Been looking for him ever since
This is my Courier, which despite it beginnings, evolved in to sort of a 'tweener. Fast, but not that fast. More of an all-rounder in the end.
