A recommended paper was discussed at 80 or 90 g.
IIRC, it was a switch from 90g to 85g that made the Quo Vadis journal go from "great" to "crap" IMHO. But that was Clairfontain paper ... my limited experience with the tomoe river stuff is it's much different (feels more like a thin sheet of plastic trying to be like paper) so it has its own issues ... pros and cons ... but most important is: it's different than the stuff we were talking about in the 80g--90g range.
