I stole kjl's picture here but I want to bring it up, it's the picture on the right on a relatively "normal" run-not bowl shaped, carved all the way around, exiting with a little speed, not ending up on a flat board in the last 180 degrees. I don't think it's possible.
Carving like the picture on the left, sure, no problem. Doing it with a "V" shaped fall line, yes. Slowing way down and flattening the board at the top, yes, I've done that too.
But like the picture on the right without a crutch, well, I've got my 10$ in to see it.
