I asked John about that roll (there is just one), and he says it was a special order, so it is actually the softest grade, and would correspond to Nuance "Soft" (the grade I use most, but the roll is too big for my Rotatrim, or else I would have bought it myself).
If Freestyle is using the 2/3/4 system then, that roll corresponds to Freestyle's "2."
Don't think in terms of "a true grade 2." It just makes it more confusing. Compared to other papers, Nuance Soft (Freestyle 2) is softer than most "grade 2" and Nuance Normal (Freestyle 3) is harder than most "grade 2" papers but softer than most "grade 3" papers.
