For what it’s worth, in the picture above, the first putter is one from their Giant line which have thicker diameter shafts and thicker lines. I know the white lines do not all have the same width as each other even in the non-Giant lines either. Have no clue about the dots, but to me they all seem to serve the same purpose.
