Dave, One reason for the staining approach is to allow me to be more productive in the darkroom. Less time spent in test prints etc.to reach satisfactory results would make my life easier. I also tend to shoot a fair amount of subjects of significant contrast so I anticipate some benefit here as well. Am I wrong in these assumptions?
You're not wrong, as I wrote earlier, I use the stuff to render the negs easier to print, and for no other reason. I like to keep the necessity for dodging and burning to a minimum.
