well, all I have is M and V3..so a lot of this would have to be speculative..;)
Actually, I use Mike and Vickie RR a lot, because I don't have access to many of the INJ/REM items , and I guess Male figures will be a problem; I've got HIM, Maya Dude, and Dork (which I've used only in my 1st pic all those years ago..;),

Females are V1RR, V3, Maya Doll, HER, and that's about it

On the other hand, I use various critters quite a bit..;) (Sixus, Blacksmith, etc)

I wish I'd said that.. The Staircase Wit
