Not only can you variate tricks using different variations for different visual appeal, but you can also variate tricks by changing the landing stance (which also affects amount of rotation) which opens up the paths to different transitions.
Pretty simple to understand. The round kick variation at the end of the move does not affect the total rotation, it does require that the performer open up sightly early, but it still lands in complete.
An outside crescent kick that lands in complete and the kicking leg. There is some gray-area between a Shuriken and an Illusion, the two main differences being that Shurikens tend to land on the kicking leg and maintain inversion.
Similar to a gymnast's pike position, the Double Leg variation is based on the Double Leg (duh) and can be appended to the end of a move without changing the amount of in-air rotation and landing in complete.
Similar to a gymnast's straddle position or "split-kick", the Crowd Awakener variation can be appended to the end of a move without changing the amount of in-air rotation and landing in complete. The Crowd Awakener variation can be learned by mastering both the Round and Shuriken Variation, and doing them at the same time.
