This category encompasses all tricks that initiate from "outside stance". These tricks tend to all occur off-axis with varying levels of inversion. Note that Sideflip Tricks don't necessarily have to takeoff from Outside Stance, but can also takeoff from Inside Stance. It has been included in this category for the sake of symmetry. Arguably Sideflips and Doublelegs have a lot in common, but the inversion level and difference in technique have warranted them to be separate categories.
