I have a somewhat muscular character that I am working on, and thought this body was about perfect... http://www.bigbadtoystore.com/bbts/product.aspx?product=TRD10013&mode=retail
but I have no idea what heads would work for it. The neck post looks like it should fit an Obitsu slim just fine (maybe with a touch of modding, perhaps). Those with more knowledge about these sorts of things... does it look like that to you? Or no?
EDIT: Ok, so that body isn't gonna work, given the pre-order state of things. So, how about this one? http://www.bigbadtoystore.com/bbts/product.aspx?product=TTL10010&mode=retail
Same questions about before... does it look like it would fit an Obitsu slim head, with or without mod? (The difference in color would be no issue, as I will have to be painting the whole thing anyway to get the skin color I need for this character.)
