what matters to me about the feel, is that a lot of experienced and thoughtful photographers talk about feel. since i have no experience compared to them, i would like to at least at some small level be able to further understand. sorry if its a let down answer
also, im not understanding your comment that a rag paper is more of a feel than a look? to me, the surface of a paper varies and looks different. ive compared prints from epson luster, gfs, platine and SR and i can tell them apart. in SR i can see what looks like a fiber direction ie the grain aligning to the long side of the paper. i do get it (feel) in general i think, a cotton rag vs. alpha cellulose?
anyway, just after i got my new printer (a couple or three weeks ago) i wondered why its so important to have thick papers. maybe i like thinner more flexible papers. but i may have to let that idea go if a thinner paper doesnt meet other priorities that ive have. so right now my only understanding is "in the old days, photographers only had thick rigid paper".
back when i first started learning on the r2400, i think i just accepted a lot of the buzz words and such.
this time around i think im exploring more of what appeals to me. but i want to be respectful of more experienced people and at least try to understand.
thanks,
