However, even though toning is "one more variable", I still love toned results on most papers. It really transforms MGIV paper prints, but like you imply, is less of a necessity, or even undesirable, with MGFB Warmtone. I have found tones to easily become to "warm" or especially nasty "orange" while sepia toning the Warmtone paper. You really have to do partial tonings with Warmtone. Not a problem with MGIV.
