im doing exactly the same thing, reinforced is the best IMO, i have all my stored ones at g4 as that si relativly easy to get the mats for the 'very rare' needed for g5 is almost impossible to find iv spent abotu 10 hours searching in the right places for one and nothing, and for a max boost of 2% id rather have more roles at a slightly lower then a g5 one, i mean im on normal shields at g4 with 5500 shields (not in scb) so with priosnmatics i think ill easilly hit 6k
I just bought Prismatics in all the common sizes and was wondering what mods would be best too. I usually go for Thermal Resistance on my shields but I'm not sure if that's as relevant/useful now?
That's been my thinking too.
On my FdL I currently have a 5A Shield Gen with G3 Thermal, x2 G4 Resistance Augmented Boosters and x2 GA Heavy Duty Boosters, along with x2 4A SCBs... although I was planning on fitting a 4A Prismatic with a 5A and 4A SCB.
They're available at all stations that sell A rated shields. Not hard to find once they're unlocked.
You won't have access to them until after 7am tomorrow when the Power Play cycle resets though.
I believe they hynt you for 3 days and then your free. I seriously doubt that will happen. I have been with her for about 4 weeks too....entered numerous hostile systems.....not a peep. They really need to look at power play....other than the enhanced modules its seems to be a yawner....
..... thank you 17 draconis 
Depends on the ship but I'd go reinforced all the way. Prismatics already have a slow load time, generally (for me at least) they are also on tank ships (Corvette) or trading/smuggling/non-combat ships (Cutter). If they go down I should already be 90% done with escaping or more so can find a safe place to disable boosters and wait for the recharge.
On my in/out of combat ships I fit biweave with thermal resist.
Depends on the build though really. Ask yourself at what point your shields drop and what you are usually doing with your ship. If you are in/out of combat you probably don't want prismatics. If you are tanking shields with tons of boosters etc the extra shield % will be worth making your already terrible recharge a bit worse.
