I've been on this Adonal thing for a while but still use D76 1:3 regularly. As an Adonal aside, attached is a 300 DPI color scan of a 5x7 print, G1 Ilford Multigrade RC. It's a nothing scene almost exactly down-sun at 16:00hrs., Tri-X at EI 1000 stand developed in Adonal 1:100 for 60 minutes at about 69 degrees. The upper line on the image is one inch on the print. The lower line is 16mm on the print, so 1mm on the negative.
If you're one of those micro grain folks this just won't cut it but, even at 16x20, I don't mind it at all.
