Amarsh,
PRPFX is the only fund of the 3 I've followed some. I too share your optimism for the fund though not everyone does. I see it still gets 5 stars from M* at least. Whenever I consider geopolitical tensions and other instabilities it doesn't seem to me that gold will play a very stagnant game going forward. It does have a timeless value. None of us can be 100% certain of course but in my opinion it seems like it would fit into a plan to help accomplish what you are expecting.
Bill.
