I've had a couple bows that had so-called checkering in the grip area. It was more like course chicken scratches, and in my opinion detracted from what was otherwise a beautiful high end bow. Not sure why some of the well known bowyers would even offer that quality of checkering on their bows.
If I were wanting checkering on my bow, I would send it off to a professional gun checkerer and have them put in some Fleur De'Lis or other fancy pattern and really add to the quality and value of the bow.
