This is a hard trick to learn and you should learn a B/S pop-shove first. You have to be able to F/S 180 before you try this.
Pop down like a F/S 180 but shove your board with your feet instead of guiding it around like a 180. The board doesn't stay under your feet so you have to find out where the board goes and next time just towards that spot. Always stay overtop of the board. When you come to landing it don't be afraid. Just look down and the board should be there if it isn't… Well your screwed. Try it again. Always keep an eye on the board and make sure it spins the 180 before you try to land on it.
Good Luck!
