a great little ship pack; i love the focus on quality over quantity. haven't had the chance to play with the lowtech ships yet but i've been liking the voltaire, carnelian, and fluorspar quite a lot (mostly the fluorspar). in particular i'm a big fan of the alternate color options on the fluorspar -- i've been brainstorming ideas for a "paintjob" mod for a while now using the same decal system as d-mods, but doing it as a swappable hullmod is a much simpler solution, tbh.
speaking of fluorspar, below are a few builds i found effective, for whoever wants them. build 1 is a player fit with modded weapons and hullmods, build 2 is a vanilla player fit, and build 3 is an ai-friendly vanilla fit.
build 1: to no-one's surprise, PD assault conversion is a goddamn house on this thing. the Magellan heavy flenser puts out great HE damage even when it isn't crit-boosted by the shipsystem, and all of the weapons reach at least 600 range with the elite PD skill. converted hangar is very nice since you have next to no slots available for acutal PD. the fluorspar's sole weakness (in my opinion) is that it's vulnerable to fighter swarms when cut off from the rest of the fleet -- which should be all of the time, you want to be flanking and ganking as much as possible in this ship. interceptor choice is up to you: i prefer DME dards for cheapness and their EMP missiles, but wasps are perfectly fine too.
build 2: more flux-intensive than the previous build, but the DPS is decent and the fluorspar's sheer speed and native bonus to active vent rate should allow a decent player to do very well with it. heavy needler works instead of the ion pulser, but i prefer pulser as it allows you to score easier mobility kills and disable threatening weapons when you're soloing capitals.
build 3: an ai-friendly version of the vanilla fit. flux-neutral at the cost of anti-armor DPS, though the single AMB should make up for it and also gives the ship a quasi-torpedo strike option. pair with an aggressive or reckless officer. systems expertise, ordnance expertise, and gunnery implants are the bare-minimum skills to really make the build shine. elite helmsmanship is solid for the +55 speed bonus while not generating flux, and targeting analysis is never a bad pick either.
