I never cared for the Aerotech system, because there was no real "movement" modifier for fast, maneuverable fighters compared to slow and less-agile gun platforms. To me, it removes half of the point in maneuvering. In most cases, the biggest guns win, unless the more agile ships can win initiative repeatedly and stay out of the bigger ships' firing arcs entirely.
On the other hand, the light fighters have so much Structural Integrity that it takes more time to destroy the internals than the thin armor. On the bigger ships, the armor holds out close to forever, but once penetrated, the Structural Integrity is gone in a couple of hits. It makes very little sense in more than a few respects, and I don't like it. Maybe it's changed since I last played it, but it never really kept me interested.
I'm somewhat more fond of the "Full Thrust" rules, at least for capital ship actions. That game's handling of fighter combat is kind of simplistic, but the capitals seem to work well.
