Perfectly heartlined zero-g roll!

Unlike NL, On Sm You can create a Dive Loop/Immelman instantly. Even under 1 minute if your hand was fast enough..I can create a Dive Loop/Immelman easily and have it smooth at the same time[approve]

I can do it in NL quicker than SM. However, I doubt the SM version will be heartlined as its still pretty hard to determine that.

The immelman on my Medusa coaster is heartlined, smooth, but looks weird.
