After reading the above posting, I realized it's hard to compare
Trial-130119/Dimezone with XTOL because they're separated by two
images. Here they are together, so you can switch back and forth
between them with one click:  XTOL:130201-D400-F1320-Xtol-
Ctr13R.jpg T119/Dime:130201-D400-F1318-T123Dime-Ctr13R.jpg  Some
more ideas I have are to (1) eliminate the crystallization issue
by replacing metaborate with TEA, because I doubt there will be
much difference between 85% and 99% TEA, (2) replace some of the
poorly-soluble ascorbic acid with better-soluble hydroquinone to
maintain a high concentration-ratio, and (3) adjust pH downward
with citric acid. Too many ideas to try and too little time...
