Informal poll - which Op Rescue story was your favorite?

I know the reaction to Op Rescue: In Plain Sight has been very significant (judging by comments and kudos). That makes me wonder if the audience as a whole considers this better than, on par with, or less than Op Rescue: New Co-Ed. The main reason I ask is that while New Co-Ed has a lot of hits, it has few kudos. That makes me wonder if it was as good as my latest effort, or worse. Or is it an artifact of posting a link to a PDF file (as opposed to a 450+ page story in the form!) so the kudo button wasn't accessible? Was it because New Co-Ed was too long for most people's tastes?

Just curious, since the perception of characters will influence future stories in this and other universes.

Also, does having a story in a PDF link affect your ability or willingness to give kudos or leave feedback / comments?
