Perhaps some of the problems with head strikes and whatnot with the Harman paper might be more related to poor manufacturing and quality control with the paper. If they can't roll the paper onto a spool in the right direction, what else can they get wrong in more critical parts of the manufacturing process?
I may try this paper at some point (I am still interested in testing for archivability, fading, etc.), but it does seem overpriced, especially if it's spooled wrong side out.
