Thanks.  Yes you got the problem.  The thing is, in order to raise the 
specular and reduce the roughness keyword, and still get the desired 
appearance, I think I need to increase the actual micro roughness of the 
surface in order spread out the highlight, else it looks a little too 
shiny and molten. The surface of the wood has a gentle scalloping and a 
lot of random knicks like it was worked with a draw knife .
