Thank you Ian.
  Black-and-white processing almost always starts with on of my presets in Lightroom. They have grown an now they are: bw, bw rehearsal standar, bw extreme, bw landscape, bw Marcos  

 , bw fake recovery, bw sweetness (I´m not sure this is originally mine), bw camera, bw almost Nikon, bw almost nikon II. 
  I do use the binary preset from Nikon here and there too.
