I agree with Chris' ideas of these Sky tracks and our City tracks being two separate concepts. Having the sky tracks going through remote, high mountain tops barely being suspended by possibly shoddy constructed suspension wires for holding up the tracks while passing through ominous and stormy thunderclouds certainly sounds different from something you'd find suspended high in a city, even if that city is futuristic. Although having that city in the far distance could be a good idea...
That being said, it's probably important to note (although you've probably noticed it already yourself chris
) that the community wants some kind of city track suspended toward the skyscrapers.
I can see the ideas of a city track being visually breath-taking, but i thoroughly approve of your decision to create balanced, fun, and interesting track design over the community's cries of "I WANT TO DRIVE ON THE SIDE OF A ***DAMN SKYSCRAPER!!!!1!" I think i speak for everyone when i say all the visuals in the world on one map doesn't amount to anything if the track itself is garbage.
