I mix my own Defender D-55 or Ansco 130 for printing with Forte PWT. The D-55 is a very clean developer, producing a good tonal range. However the Forte suffers the greenish cast in it. The Ansco is also very good, but expensive and the glycin can be somewhat tougher to dissolve. Since I tone all prints in Nelsons Gold Toner, the cast has not been a problem. However, I was wondering if the formulas for the Edwal, or Zonal Pro were available anywhere? I don't usually buy any chemistry off the shelf anymore, prefering to mix and tweak my own.
Ansco 130 is worth trying because it has a very long tray life, something you mentioned as being important. I've not yet tried it with Forte papers (although I will soon), it is a beautiful developer with the Ilford and Agfa papers with which I've used it. Greater dilution results in softer contrast and a warmer tone.

Any information on substituding Sodium Carbonate for the Potassium Carbonate? I'm thinking the sodium compound would be very similar, but would require a different dilution. I've got a lot of it here and could compare the developer against the original D-55 and the Ansco 135 formula. The 135 does a nice job with Forte papers and doesn't produce the green cast.
