Those are all attractive looking options. My only worry with the Russian ones, is that they are already 25 years old. Maybe they can last a long time, but I have some experience repairing Soviet made equipment, and their electrolytics are always bad, almost as a rule. Hopefully the paper ones are better! They sure look cool though

the paper in oil?
I plan on testing them each for leakage before use
Yes, russian PIO's
I have one right now in my older DIY amp squeaking after testing 3 yrs ago
My plan is to let them sit at 400VDC with a bench power supply and measure leakage with my Simpson 260 on the 50uA scale, before I go ahead and put them into the amplifiers. I don't have an actual capacitor leakage tester but I think this improvisation should be good enough to check things out.. got plenty of old wax caps and new orange drop/dip types to use as a baseline.
