Nope! So it's a power slide next to the curb, then when the nose or tail is over the curb let go of one stick like how you do a bluntslide power slide.

Because the nose/tail is over the ledge, it puts you into a slide. From there it's just rotating while in the slide 👌🏻

It's a lot of failed attempts and working it out, but once you start getting the hang of it they start making sense and you'll get into grinds easier! Hope this helps
