Are there any skycurve maps?

I've only owned this game for around two months, and I've only closely followed it for about seven months, so I imagined I've missed some pretty cool maps. Specifically, I want more skycurves like the one in gridmap. They're like a combination of racetracks and rollercoasters, but unfornately I've learned gridmap's skycurve all too well. I need some new loops to throw my car at. Anyone got anything?

Thanks for any help.

 

I remember the maps from mike22 but I don't know if they are still working in the actual version.
