The Dork and Posette have plenty of clothing, but nothing new for quite a while, so the Dork and Posette fanciers will appreciate anything new and different for them. Don and Judy never got much of anything, so the few folks who like those two would appreciate anything. V3 and M3 have the most play at the moment, lots more for V3 than M3. So more people will actually use what you make for them. David and SP3 have damn little designed for them, even though, IMHO, they're the best of the figures out there. I'd certainly appreciate more for them. And don't forget Luke and Laura, who are in real danger fo the same thing that happened to the original Mill kids, no support. In other words, pick one, pick all, and someone will appreciate it.
