I'm used to mapnik zoom levels, I'll have to figure out what 1:25000
represents, although I haven't really started on a style sheet yet.

something like highway=track, grade=3 ?

I think AS2156 sets minimum standards for the entire track, in other
words what is the worst to expect from this track... Although we could
tag various section of track at different ratings...

I'd suggest that we try tagging and then rendering some/all of these
suggestions and see what works best then we can have another go at
documenting it for actual use, I generally don't put much stock in the
voting system...

Have these features been added to OSM? If so we can try and start to
render them. Also what is the lat/lon of the area?
