Dissolving the FeOx "faster" is a nice plus, but the real difference seems
to come in the paper speed. I get up to a stop's worth of speed gain when I
add EDTA to the FeOx and it has a longer shelf life, too. What do you mean
by becoming "unavailable for the rest of the process?" I've never seen any
adverse effects with the EDTA/FeOx in terms of density or dMax loss.
