Why 8A.NU don't use slash grade,if i remember at the beginning of 8A.NU the 8A members could use slash grade for the hard ascents (like 8C/C+ or 8C+/9A...)?
In some few cases in the beginning until 2002 I think, it was possible to ad slash grades. However, later we come to the opinion that grades can never be so important that we need half grades, especially since some of these grades where downgraded 1.5 grades.
