Bill this little mistake ratcheted up my diligence that was probably (obviously) severely lacking. I used to spreadsheet all my temperatures/formulas/mixes (date mixed, even periodic hypo and clip tests) and I got lazy. The amount of effort required to test for "active" fixer or developer is so small that if you really want that roll or rolls to come out it makes sense to me to do periodic staggered sampling just to make sure...

Thanks again!
