Too over-the-top for my tastes.  The reason none of the exiting long, curly hair models work is:

 A.  Gravity not taken into account, the pull of the long curl on the top of the head is going to straighten things out at the root to the ear.  

B.  Flax.  Not enough polys creates flaxen straw bends that look like twigs instead of natural waves, spirals and curls

C.  Collision.  In trying to keep it from being a rats-nest, modelers tend to poof it out too much at the sides in order to keep the polygons from intersecting. 

What's really needed is a way to dynamically layer one group on top of the other in a simulation, such as what Marvelous designer does for clothes so that ultimately the hair model itself can be fairly "together" when exported from such a simulation

 D.  Modelers tend to go too short or too long...there is a sweet spot that just keeps getting totally missed that morphs just can't fix.

 

SAV has come close a few times and I often do use them for lack of better...but (and yes I am an armchair critic) from the cheap seats, it's bloody 2014 the tools and talent should be available to make this happen.  In fact, I'm fairly sure this is what it would take to reignite my love for Poser.
