Stephen-
If you are looking for a tactile experience, you are likely to be sticking with cotton based papers and not alpha cellulose papers. The short reason is that you are more likely to find more pronounced texture on a cotton based paper. I don't know of any other double sided, light(ish) weight cotton paper out there other than the Entrada 190gsm.
Just as a side bar, I do consulting work for Moab by Legion Paper, just for full disclosure.
