I bought a 4900 a few months ago to get into printing, and at the time, knowing that I was probably going to have some growing pains, I just picked up a cheap roll of Epson Ultra Premium Luster to work with. (And lurked the hell out of this forum.) It turned out I figured things out faster than expected, got prints I was really happy with almost right off the bat, and have worked through about half of my portfolio. I gave a bunch of prints away as Christmas presents, and they were universally well-received; then I got distracted printing and selling 5x7 cards, and between the two I now have people asking to buy large prints. However, I'm sort of hesitant to do so without exploring the available papers more thoroughly. I got an Epson sample pack, but my conclusion from that was I actually like the UPL as well as their fine art papers. Exhibition Fiber strikes me as very slightly better, but is also more fragile, not to mention much more expensive. Between Cold/Hot Press Natural and Velvet, I've come to the conclusion that I dislike textured matte papers. I'm fine with the very marginal texture on the Red River Polar Matte that I'm using for cards, at least at that size, and HPN isn't too bad, but CPN and Velvet really bug me.
So now I'm wondering if I should just be pleased at having a cheap paper that I like, or if it would be worthwhile to spend some time getting sample packs from third parties, and if so, which ones I should be looking at. I'm printing color, mostly 15x10 and 15x12, but enough panoramas that I need roll paper.
Thanks for your input.
