I am indeed using alot of Cycles nodes, at least.  Here's my attempt to show as much of my shader as I can at one time.

Skin_Hair_Blend_Diff plugs into Alternate_Diffuse, and Skin_Hair_Blend_Spec plugs into Alternate_Specular.  The Skin_Diffuse_Map is plugged into main Diffuse with its value set to 0.  The stuff on he right is just doing math on input maps to generate a final hair mask based on user settings.  I also make heavy use of customized compound nodes to aid in organization and the reduction of clutter.  The main selling point of this product is that it enables the user to control various aspects of the shader (skin color, eye color, hair color, presence or absence of freckles, etc) via parameter dials instead of fixed presets.  That's why it has to be so complex.  The default dial settings produce this when rendered.

As it stands, the buck stops with a PoserSurface node activated as both a SuperFly Root and a FireFly Root.  I'll experiment with using separate roots and see if that helps.  Thanks!
