I've recently tried the D-23/Kodalk solution soup. I like the tonality of the prints I made from a roll of APX25 120 but blowing them up to 11x14 showed that the grain was a bit mushy. Hard to quantify but not exactly tack sharp like I get with Rodinal (for example) and APX25.(posted 8175 days ago)I've been planning on trying Barry Thornton's Metol 2-bath. It's very similar to the D-23 but cuts back on the Sodium Sulphite for increased sharpness and acutance.
