and a bit more tweaking
I decided to keep the 20mm I've been using on my other ships, mostly because I don't really want to have to go back and swap every one of them out.
Light armament has been changed to 40 x 40mm (3 x 4; 14 x 2) and 44 x 20mm (22 x 2)
EDIT: thought I might include what I came up with in SS too. Not sure how accurate I got. I always worry about that.
