Well, the good news is that they all tend to print in a similar way. In my experience, techniques developed on 250gsm Rives BFK will work about the same on the 175gsm Rives BFK Heavyweight, or is that the Rives Heavyweight BFK? You have to laugh.

For instance, Daniel Smith carries a 250gsm Rives White, and a 270gsm White, not to be confused with the 280 gsm BFK heavyweight. There is also a 175 gsm Rives Heavyweight BFK, not to be confused with the 115gsm Rives BFK lightweight, or the 180 gsm Velin Cuve Rives BFK. It is crazy-making to be sure. I like the strangely named 175gsm Rives BFK Heavyweight for pt and gum. Good wet strength and a nice strong pt print when it is acidified.

It is surprising since the surface is softer with some texture. It does take a bit more concentrated PVA size. I looked around and to my surprise Rives BFK comes in only one flavor, but many colors. It is possible that what was made years ago is a different paper that is sold today.
