Maybe they replaced the para-Phenylenediamine (hereafter “PPD) with CD3? For a time within the last 3-4 years, PPD had been difficult to obtain; Photographer’s Formulary had quit selling it; they stock it as of today, but it’s also one of those Certain Death On Contact chemicals CD3 is supposed to replace. Therefore one doubts it will appear in 777 in the Bluegrass product again. As has been said before, the formulas change over time. If the new stuff isn’t up to par, it dies off; remember New Coke..?
I myself remain intrigued by the Germain Fine Grain (hereafter, “GFG”) formula in the Unblinking Eye article, and may give that stuff a try. IMHO, any film developer you can drink and not die a horrible death (viz., Caffenol), isn’t worth beans. GFG is simply loaded with carcinogens, mutagens, and other -gens that are only shippable by UPS Ground—if at all—so it must be pretty good, right?
I have yet to read of any A/B comparison between GFG and 777, so it might be an idea to shoot two identical rolls of film, same subjects and exposures, send a roll to a 777 user, develop one in GFG, then have both of us send the negs to a third party here who could make scans/prints off both rolls and evaluate them for comparison. I think such an experiment would answer a lot of questions, and once the second film back for my RB67 arrives, the exposure process would be a cinch.
I wouldn’t want to kill off the business of making & distributing 777, but if GFG does the same job, it’d be less trouble to make, yais?
