Nice topo Neil - I may be heading back to taipan for a few weeks (!) around christmas/new years and might have to give your new route a quick look. Some ideas re: the guide - Is it possible / are you already indicating whether abseils require single or double rope on the topo? I see in the topo on your smugmug site that the abseil point has an arrow with a white circle and black inside - perhaps this black centre could be half white to indicate it only requires one rope? Please forgive my ignorance if you're already doing this.
Another thing I think is interesting is hollow stars. These are the stars a first ascentionist gives out, usually to their own routes (!). With subsequent ascents, the quality of the route is confirmed or denied and the stars becomes solid.
