dango77 - thanks mate. yeah - i really don't get some of the gripes that people have with zbrush. it handles things differently, but iut's fun to use. and it still confuses me, but so does maya!
murambi - hey - thanks mate - tho i'm not sure what picture you're referring to. i tried to avoid using any tris in this model as i knew i was taking it in zbrush. i think it can convert your mesh when you import it - tho i think you want to avoid any triangles because z only divides squares into triangles, so if you have a triangle on it's own, the displacement will act weird in that place. i don't know if that's definitely true or not, that's just from my own experience with my frog mode. hope that helps.
