I voted half and half (guess it depends on WHO you want to read about as to which half gets what).
Personally, I like to read about Miley Cyrus as a villainess, so the more I see about just how low-down, dirty, and devious she can be, the better. (If someone else sees her as a heroine, or a jobber, they'd probably not want to read that in a long form. So good luck with that!)
BUT, on any card....in my opinion...if a bout "deserves" to be a main event, it "deserves" a full write-up.
Difficult decisions for you, and no help here probably, but I RESPECT you for asking the readers for their preferences (hope the votes help you in that decision).
