Which heavy fighter and what codies? O-O

[Anaximander]

This might not be exactly what you are looking for, but I find that a Lynx with 4 Claymores + 2 Culverins + MR does the job well. It has thick armor, it's reasonably fast and have a big powercore. And those guns hurt a lot. 6860 hull damage per shot without the MR.

If you like lighter ships, get a shotgun eagle.

Or Outcast Wyrm Bayo and no codes.
