Well, most DAZ MAT files I have work well in poser5. I found that they do tend to work better if you invoke them from the material room rather than from the pose room, though. As for the "split end look", I don't really understand what you mean (english is not my native language), but have you tried the displacement trick ? (you plug the texture to the displacement node, and set the displacement value at 0.001). Hope this helps.
