My Strategy Guide found here...

Thanks for putting this together. I had discovered most of it myself, but thanks for the protip about the fighters. I think perhaps you're a little too dismissive of the ships though.

EDIT - after playing through a few more times, I think you're spot-on on your recommendation to use lasers exclusively as your point defense weapon and to focus on a single "big" gun. So far I've had the most luck with projectile turrets and have had the least luck with lasers. Everything else is somewhere in the middle.

I'm also enjoying your strategy of building a horde of tiny ships and racing around laser-ing everything to death. It's incredible how much damage those little point defense lasers can accumulate en masse.
