Do not automaticaly exclude all green sensitizing dyes from the red sensitizing list. When I started working with green sensitive SDE3008, I got very frustrated when my "green sensitized" emulsions, with only SDE3008 kept turning bright violet. I, in fact, had a panchro emulsion and did not know it. It did not seam funny at the time. But I was shure I had not made an adition mistake. Yet the evidence said I had. Or so I thought.
As it is turning out, I do not need a second dye, SDA3057, for red sensitzation.
