Ruby gold electrolytic capacitors?

Has anyone had any experiences with the new(ish) Ruby Gold electrolytic capacitors? One of the power supply caps in my Bogen is running 469 volts, so I am fairly limited in selection (450v seems to be the standard in high voltage 47uF capacitors).

I am looking at a Ruby 47uF 500 volt 105C temp rating capacitor and a German F&T 47uF 500 volt 85C temp rating capacitor. I'm leaning towards the Ruby because of the higher temp rating but choosing Chinese manufactured vs German is against my better judgement!

I've used them several times over the past five or so years when Sprague or F&T's weren't available and so far (knock wood)
haven't had a problem.
