Microphen isn't the only speed increasing developer available. I agree that something like it (phenidone, no?) will be better than D76, but it doesn't HAVE to be Microphen. I can tell you from experience that T-Max developer works beautifully, and I'd guess that Xtol would work well too, though I have no experience with it and this film.

Where this film really becomes superb, IMHO, is in 120. Now if I get around to shelling out the money for that 80mm 1.9 for my Mamiya...
