Search reviews for a name of " and ".  You'll get reviews for ladies who have "and" in their names, but you'll also get lots of reviews for duos. By default the most recent reviews sort first, so that works for your request for input on duos seen lately.  Those reviews have a lot more info than you'll get from posts here.

(P..S. Probably won't help to search on "&", as it appears those reviews are all fairly old.)
