I am like you, wondering. I tested a batch early last year and it was good so I bought a bunch. Then I tested another batch about 6 months ago and it was terrible. I have a friend here who just tested it a couple weeks ago and said the same as you. The PF people said the problem was solved and the guy back east who sells the Westons Parchment said it is a matter of good and bad batches. I wonder if you were to order some from a regular paper supplier and tried the bright white and the ivory as well as the Natural white you might find one that works. If you do, don't tell anyone till you buy all you can afford.
