Tempest: What's the point of the pulse laser? You're already way over flux budget with just the heavy blaster, so it's not really adding anything.
My general tempest fit is one heavy blaster, Hardened Shields built-in, either Extended Shields or Hardened Subsystems built in (depending on whether or not you've got Wolfpack Tactics; if you do, you can skip Hardened Subsystems.), then in rough order of priority, extended shields (if not built-in), resistant flux conduits, max vents, max capacitors, flux distributor, accelerated shields, flux coil adjunct, solar shielding, and then maybe something in the missile slot or ITU or turret gyros or whatever you've got OP left for.
This works with Special Modifications, too, it's just that there you won't get past the 'max capacitors' step of the loadout; you'll end up with one heavy blaster, resistant flux conduits, 20 vents, 15 capacitors, and whatever three hull mods you've built in - Hardened & Extended shields are requirements; Hardened Subsystems may also be required.
Solar Shielding may get pushed up the priority if you know you'll mostly be fighting remnants or other high-tech opponents. Or, alternatively, it gets pushed up in priority if every other ship in your fleet already has it - I did run a game recently where I just put Solar Shielding on everything and it was a very nice quality-of-life thing to be able to just about ignore hyperspace storms.
