... sure like those manual reset carts.
Where did you find those?
I'm using your C6b base, and Premier Art FineArt Smooth 205.
...
Isn't EEM the same paper, ...
No, it's the Epson Premier Art Scrapbook paper that is the same.
... I thought it best to stick with one combination ...
I think specializing in one or a few is the way to go.
... I do want to try that relatively new Epson Hot Press Natural you've mentioned, ...
Yes, it may be the one to concentrate on if and when PA 205 and Epson Premier Art Scrapbook disappear. My long term favorite the PA 325 is apparently scheduled to end when the current input rolls are all cut and sold.
I'm currently concentrating on Arches full sheets (22x30") for high end, non-panoramic. (I sell mostly the glossy Noritsu dye prints to the random gallery walk-by audience.)
(BTW, when it comes to high end, the issue of limited edition and how to best apply it to the type of photography I do becomes a very complex and interesting issue. My current conclusion and approach is really bizarre by the standards of standard art collecting. See http://www.paulroark.com/Limited-Editions.html )
