In reply to Offwidth:
Let's face reality here. Lots of indoor bouldering walls use V grades. For simplicity they start at V0 then V1 etc. Beginners don't want to cope with nomenclature such as V0-, V0+ etc (nor does anyone else for that matter).
Therefore, V0 and V1 are going to be novice/warm-up sort of difficulties, which means starting around 4b and 4c. Further, since loads of people boulder indoors, these grades are going to creep outside also.
Anyhow, outdoor bouldering grades have never made the slightest sense to me (even internally within a system). The new Rockfax may have the beginnings of rational system, though I haven't got it yet so can't tell.
PS I think Sherman should be shot for inventing a system starting at very hard problems.
PPS Whoever invented putting font grades in the same typography as French grades and English tech should also be shot (though I do realise that all these originated as the same system, and then diverged).
