Thanks, the H by H original was a favorite of mine too, apart from the incredibly fierce curl on rolls, that defied flattening, and which some LF Epson printers simply couldn't handle.
Great surface though, really like the old Baryta darkroom papers.
So rare that some claim by the marketing department is completely accurate!
I don't know much about the new X variant, but will give it a look.
Appreciate the reminder!
