Yes I use them all the time and only on the Z.
I've used and tested just about all of these on the Z the last two years. What I use now almost exclusively is Hahnemuhle Photorag Barya a non-oba, in roll form, and also the new Cone Type 5 fiber gloss that is similar but better than Crane Silver Rag. I'm testing that one now and it looks really promising, especially for black and white gelatin silver clones.
For brighter surfaces with oba by far my favorite is Innova Semi-Matte ( called satin in Europe). I really wish they had made this in a non-oba and then it would be my pick for #1. It has the perfect texture and the least gloss differential issues of them all, but it a little on bluish white side. The other good ones are Crane Silver Rag ( non-oba) and Innova Ultra-Smooth Gloss ( aka Epson Exhibition Fiber also with oba ), which also comes in all the roll sizes.
Although I had the new star wheel assembly installed after a year and a half, I never had the Tan rollers installed because I haven't had any negative issues ever with any of the above papers. The only paper I ever saw roller marks on was the Harmon Gloss and that was before the adjustable star wheel assembly was installed. The Harmon looks plastic to me so I don't use it. I have quit using the Ilford Gallerie Gold because of unacceptable bronzing and gloss differential, especially with black and white and is SCRATCHES really easily. I tried the Canson Platinum Rag and it seemed fine but I still like H. Photorag Baryta the best overall. The new Hahnemuhle Baryta Fiber Base has an improved texture over the earlier also bright Fine Art Baryta but with a strange pinkish hue to the base. Don't know what they were thinking about with that. Look at it in daylight and you will laugh out loud. Otherwise it would be nice.

Hi,
I hope you have the updated pinch rollers (tan in color), as opposed to the original black ones. The black ones really chewed up the baryta.
But with the tan ones and the newest revision of the platen it does work with these delicate papers.
So long for now, TOM
