Spot on as usual Tinny.
I too prefer the hypsometric tinting of the WACs as well as the two o'clock shadow. But as we know, they have not yet been produced for everywhere yet, so ONC is our next best hope. Especially in remote parts of the world.
If this is the style of map I think it is, then you can nominate the data you wish to see. I think I'll have the colour de-selected! I find it confusing to see a big green patch way up in the mountains!
