flourish

So I'm planning to buy Solo by Michael James and I want to know what flourishes I need to know before I buy? I'm in the intermediate level in cardistry, if that helps. If anyone can kindly make a list of stuff I need to learn first, it would be much appreciated. Thanks in advance!

there's this one flourish I really wanna learn, but I don't know what it's called it's driving me nuts, I don't know the name!

I am having problems with various flourishes for different reasons. Charlier cut & all one handed cuts: my hands are too tiny to hold two packets in one hand Spring: Either my thumb hurts and I can't spring the cards or I can spring but can't catch Thumb Fan: I can fan but it ends up fanning...

The following is a video of Greg Wilson during the explanation video for "Revolution". It's only 7 seconds long and nothing based on his effect is revealed, but he does a move and says how he has no idea what it's called, which sucks because I want to learn it. Any help is hugely appreciated!

I have read Royal Road, Card College, Single tutorials on sites and some videos. I can do an 'OK' one handed fan, nothing to special, but when I attempt a thumb fan it's never equal. (I have used new decks for it too.) ~DB
