Do you do the spent-developer thing after the fix with the PMK, or just rely on the wash to intensify the stain?

I found that the spent-developer thing increases ALL the stain, not just the image stain, so I can't determine whether it's worth it or not. I do, however, use an alkaline fixer (f-4 from Formulary) so that I don't have to use hypo clear and erase stain. Works great.
