the reason i dont use it is because it can be rim lit in a true 3d lighting environment. I have my own strand based hair system that i use in my animation work. this is a still from a lipsynch that is rendering in cinema4DXl right now .where mike2 is wearing a strand based U.S.marine flatop that created with cinema's hair plugin.

because the hair strands are true geometry i just apply a basic color and specular and the lighting does all the rest.
and as his head move through different lighting the highlights will change naturally much like the famed "aki Ross" in FF
of course ihave to endure longer render times but to me its worth it for the look i want.
