Less than 5 minutes video with no vocal instructions, only subtitles. Not the most detailed teaching
I've seen...
I'm only giving 4 stars and not 3, because it was cheap.
The move itself
is not that powerful as the top shot, as it will never be that fast imho. Also less impressive
because you need the momemtum of your wrist too, so the launching hand is not steady. It's rather a
throw than a shot. But you can see all these in the performance video as well.
