Available Single weight RC papers?

I'm making paper negatives and looking for single weight rc paper. Sorry for asking an old and probably exhaustively discussed question but the search function has been timing out on me plus I am looking for currently available papers which is sadly akin to watching rain forest depletion charts these days. Or national debt charts in reverse.
Thanks!

I've seen RC papers only in medium weight.
A grade 2 and 3 VC FB SW paper is available;
Fuji Rembrant via the WWW. Dan

AFAIK, no true single weight RC paper was ever made. This is due to the difficulty in lamination of the two RC layers with the thin paper. Although the newer RC papers are thinner than the RC papers from 10 - 20 years ago.

Most MFGRS are trying to exit the SW FB paper market as well, due to low sales and difficulty coating.
