Environment Probes and Material Settings

[NotSure]

I'm having problems trying to set up a material which is smooth and use the environmental probes. Like in this photo:

Should I use:

diffuse+normal+specular+env.shader

or

diffuse+normal+specular+parallax+roughness.shader

It seems to want to use a random normal map if one isn't set.

  EDIT: 

After adding a flat normal map and spec, the shader is fixed(I guess you need defaults) but roughness still doesn't seem to make the environmental probe less clear.

Looks like I over complicated things, it appears I just needed to use the default.shader to achieve the proper reflection.
