Possible Tomoegawa substitute?

I have a 1980-1990s la Pléiade edition of À la recherche du temps perdu, which is printed on thin, smooth paper reminiscent of Tomoegawa paper. According to the colophon, the paper is from Schoeller & Hoesch in Gernsbach, Germany. Schoeller & Hoesch appear to be still making paper under the name of Glatfelter Gernsbach.

Has anyone written on their papers? I’m thinking that since S&H paper was used for massive books just as Tomoegawa was, they may have similar fountain pen friendly qualities.

Not sure I have posted before so please excuse my jumping in. I have a 1970 edition of Kleist on the same paper. As you say, this company was taken over by Glatfelter in 1998. I also would be interested if they still produce this great paper or something like it.
