Thinking sales-wise (as in, to keep the album selling well over the winter months) I feel like TBC would be best. I'm good with TBC, DYTAM, or WAW next.
The only reason I'd say no to TBC is that I don't want it to get lost in the shuffle after BA. if its release next fall, it can have it's own space to shine, it will compete incredibly well with the new fall singles because it could be anyone else's first single, and it would REALLY stand out after OWT, which is sure to be the summer single.

CUPID!!!! I'm still gunning for Cupid, TBC, OWT, and WAW (currently in that order haha). Cupid has definitely become one of my top Carrie tracks, so it has got to be released sometime. I think that it being the third single would be great as it would have reached its peak by the time Valentine's Day rolls around. The amount of airplay it would get on that day alone would be enough to push it to number one if it hadn't already, and as others have said it gives us a break between the dark BA and TBC...
Too. Many. Polls.
