I think your problem with neutrality is your choice of 2 cool curves
rather than 1 warm and 1 cool. This will result in a much more
neutral tonal range.
The bronzing is not QTR's fault. It is ink used by the 2200, the
way the paper absorbs it and the way the 2200 puts ink onto the
paper. As far as I know, the only way to deal with bronzing is to
apply a coating that will even out the reflectance values of the
paper or simply change to a more matte surface paper.
