@Longman: Your pinky moves straight down, and not to the side. It's a knacky move, but keep at it, and you'll get it down eventually!
It's not a very trustworthy source though, and not ethical at all.
@maxrob22: A good source for learning Top Shot would be Lennart Green's "Green Magic volume 1". Many people think the explanation on this tape is a bit unclear, and if you happen to be one of those people, check out Ian Kendall's "
Bastard Hard Moves Made Easy". He actually has Lennart's permission to teach the move, and he goes in great detail on it. Recommended.
