Yes, Koz's hair is unparalleled. Period. All other hair models I've tryed (some very expensive) look like strips of semitranslucent plastic or worse: they do look like (badly) painted-on hair. In some cases, I could paint better with my humble mouse. I've read Koz's tutorial on creating hair in the Poser 3 paleo age. Looked simple, yet is nearly impossible to match his skills.
