Just checked the article, really good! Yes, between these tricks and illusion tracks, there's a lot to do to have the most varied tracks. One thing I like doing from time to time in my tracks is using long jumps. For some strange reason, Stunts doesn't see that ramp->space->elevated-road->ramp is not the same as ramp->elevated-road->space->ramp, so it allows you to create double-jumps this way. I'm sure there are many more tricks that could discover to enhance tracks
