Aidy Burrows quickly explores all the options in the new Principled BSDF shader node that will be available in 2.79.
Blender’s New Default All-Purpose PBR Shader!

The sneakiest PBR shader in Cycles?
The most principled shader in Cycles?
Maybe all of the above?
Will be available in Blender 2.79 - coming soon! Aidy.
