Hi guys. I need help on the advanced sleight Paul Curry Turnover. I've seen several magicians doing it and the version I read up on in a book seems to vary. I'm wondering should the sleight be done with the top card or bottom card displaced? (meaning whether should my finger hold the top or bottom card) Also, is it moving the hand inwards for the change or outwards?

You can PM Shade on this. He taught the move at our chalet last year.
