Those 'mahuds' are fairly big sculpts. They are at least as big as the Uruk-Hai, if I remember correctly (I can check later today if you'd like me to - I have already moved all my LotR stuff to the new place, but I can probably find some more stuff to move there tonight, thus having an excuse to go there).
I would certainly not consider using them for a diminutive race, though.
I can see why some people would shy away from the Kallistra pygmies, but I like them, because they remind me a lot of the pygmies in an old Donald Duck story (where they are at war with some cranes). They are VERY cartoony, and very much a caricature, but, then again, they are a 'fantasy pygmy' range.
If you want realistic pygmies, Foundry is the place to go.
