I also use the T16k, and i an thinking about adding curves (too lazy so far). But i have more issues with small twitchy target than with controlling a twitchy ship. Killing an Eagle with FAoff&fixed in any ship seems to be extremely hard, simply because the target is so small and moves fast. Maybe i switch the small fixed beams to seeker missiles, but that would be agains my idea of maximal challenge.
I find fixed hitscan weapons excellent for sniping from a distance, the small gimbal effect helps massively. A small, manoeuvrable target up close will always be harder to hit regardless of your weapons.
Seeker missiles (and lots of other weapons) are more effective than a fixed beam & FA-off, but do you want to be an effective farmer or to master a challenging craft?
Once you can hit stuff reliably FA-off with a beam, move on from there imo.
