You say your site is an authority site (not saying it isn't) but you're still out there chasing links? I would've thought authority sites do well attracting links naturally without having to trade for them.
But anyway, the reason PR is overrated at the moment is because it is pretty much the only stat that's measurable/quantifiable. I don't think you can put an exact measurement page relevance or quality content at the moment unfortunately.
