Kerik,
I would agree. I tried some FAEW and used an oxalic acid presoak with it.
I got good prints, but switched back to COT 320 because I did not like having
to do the presoak. Once I began printing with the COT 320 again, I noticed
I was not getting as good as results as before and determined that the
Potassium Oxalate that I was using had somehow changed drasticly when using the FAEW.
My guess was that it had gone very alkaline and PH tests supported this.
I threw out that batch of Potassium Oxalate and mixed fresh developer and
experienced no further problems.
