I have the Kodak chemicals from Photographer's Formulary. I mixed 500ml back on May 8th, and last week processed my 7th roll of 120 and 5th roll of 35mm on the same chemicals. The film has all been Fuji 800Z, Kodak Portra 800, and Kodak Ultramax 800 (35mm). I am not taking scientific photographs requiring perfect color, and since I am scanning I don't even really have any idea how close the exact colors are. However, I get negatives that look 'right' to me and scan fine.
Hope this helps,
