Excellent. Just the sort of advice I was looking for, thanks.

EDIT: In purely combat terms, how important are battleships with their heavy mounts, and are there improvements on them? I'm asking becasue of the emphasis people have put on the CL's 10% bonus and someone having mentioned that the heavy mount on a carrier is large and vulnerable in combat - and in simulator battles my carrier wasn't much of a fleet-conquering hero.

EDIT2: I know a methane breather who is likely to oblige - there's a lot of Oxys in this game - Do I need to remove the existing population of my domed worlds? This would be something of a project, I'd think.
