How different are the actual sizes of 10mm dwarves from different companies, such as Kallistra, Pendraken, Irregular, Copplestone, and Magister Militum? Does anyone have a pic showing all the different 10mm dwarves? I'm just trying to get a sense of which ones will mix well with each other, and see which actual scale (true 10mm or "heroic" 12 mm) is more common.
