If you subject BAD TARGETING to your visitors for a long time, even though the payout is "good", you run the risk of having visitors who never click your ads in the future. Visitors like targeted ads that benefit their web experience. They don't appreciate irrelevent topics and annoying ads.
I switched majority of my sites to adsense 1 month ago. I only have couple of low performing sites with YPN and I don't have the intention of moving them to Adsense. I gain nothing out of that.
