Have you ever seen anybody turn a card over like in Diving Board Double?
Anywho, just like everyone said, it got boring to watch all those fans and dribbles and that long long long overhand shuffle... Just make it shorter... One cut, one shuffle, and that's it.
The thing about double lift. There is nothing wrong with pulling two cards on the back. But when you do, pause a little, move your hand away from the deck, make a gesture with that hand, pick something up, just steal some time for audience to forget that little thing with your thumb that you did. And than just pick at a break, and you are good to go.
