1. What sort of ranges are we talking about here ?
2. Surely the disadvantage of the stain is that it flattens the negative.
In my experience a good clean Pt/Pd negative, for a full range of tones,
should have a density range of around 2.0, maybe a little higher. The best
developer, out of a bottle, for that range is PQ, and, for home brews. acid
amidol.
