Hey guys,
I recently got my hands on Yoann's Modern Intricacies DVD (which is amazing btw!) His DVD is clearly mean't for people already established in cardistry. Which while I consider myself to be, I have yet to learn the cardini change.
Going on the good ol' youtube I found various tutorials for the move, but they all seem to be somewhat different. I've heard some magicians use their middle finger, while most use their pinky, yet apparently the correct method is by Michael Ammar who uses his ring finger.
Could anyone please recommend a good source for learning this move? Paid material is fine of course

- Many Thanks!
