Now, I realize that no current hybrid coaster has a traditional loop of any sort.
But this does exist.
I've tried making something similar to that in the game and these were the best I could do with the limitations.
As you can see, it's close but not quite there. The current vertical limit is 85 degrees or somewhere around there, so to finish the inversion you have to start turning it and unbanking the track, which looks weird.
