Do you guys think it would be in the realm of possibility to do a fastslide/backslide rocket grab? A rocket grab is a safety grab but with your grabbed foot in the Liu Kang position. You'd have to do it lip on while keeping your grabbed foot stretched outwards until the end of the rail, and it would only work on higher rails/boxes.
Also I kinda wonder why seeing grabbed fastslide/backslides are not more common given that a ski has so many places you can grab.
What about a nose/tail press fastslide or backslide? Is that realistically possible?
