So I actually ended up buying both ships today and flew them for a couple of hours - and while both have their pros and cons I really prefer the Chieftain due to its agility, plus I don’t have to keep an eye out on the fighter - although I do miss them sometimes because they can be a great distraction vs tougher targets.
Here is the build I’m using atm, but I will likely tweak it a bit more - maybe even drop limpets once I stock up on mats and add 2 more hull reinforcements instead of cargo+collector.
I will probably try the Frag cannons at first opporunity.
I look forward to revisiting Krait once I get engineering going finally though.
