Thanks to all for playing; I thought just about every clue had clever wordplay, so as usual clues with smoother/more plausible surfaces were ranked higher.
Honorable mentions to chris 2, mprs 16, paul 3 and 21, and geeker 13 and 14. My list of finalists was mattrom 12, jono 17, ginge 18 and patrich 25.
12. With no support, wearing décolleté clothing, and drooping (11). Vivid if slightly off-putting imagery.
17. 19d persuaded bankers to launder for free (11). Works well as long as 19d is someone who can terrify a banker, perhaps Doug Piranha (bankers fear sarcasm).
18. Divorced, concentrating on killing time, hang in there (11). Very nice (would the surface work even better if the commas were question marks?).
25. Unbiased in-depth record study in hospital department (11). Intricate wordplay, smooth surface. No notes.
In the end, it was ginge 18's combo of "killing time" and "hang in there" that did it for me, so the honor of hosting next week goes to ginge for:
Divorced, concentrating on killing time, hang in there (11)
Congrats to ginge. Prize time:
