Carl,

I wonder if you tried potassium oxalate with kallitype? It would be 
interesting if it also gives smoother tones and a less gritty look in 
kallitype than the sodium citrate developer I proposed. Somewhere I 
read that potassium oxalate was very tricky to use with kallitype and 
for that reason never tried it.
