YSlow, go away! Stop dropping my score for not using CDNs! I used your fucking CDN for delivery and it was tripling my load times! I know what I'm doing, now kindly fuck off!

That said, I just have a few headers to set and images to reduce and I'll be at 100% with PageSpeed (but not YSlow because they suck). At least Google knows when CDNs are and aren't beneficial!
