PR doesn't necessarily affect your rankings. I have pr0 and pr1 pages that rank #1. I see PR5 and up pages that don't rank for anything.

I link out a lot, and I don't care about juice. My criteria is whether or not the link will enhance the user's experience. If it does, then I add it. If it doesn't, then I don't.
