Charles Bertram, the great English conjurer, used Charlier's move alot and could execute it 80 times-minute ( as mentioned in Expert Card Technique, I recall De'vo saying in a forum he could do it 120/min) ). He learned it from Charlier himself, and published his slightly modified handling in The Modern Conjurer. He also used it as a color change (angly, but neat ), see Expert Card Technique. I did the change for a friend of mine on webcam long time ago, I hope he come here and say what did he think of it. Marlo has alot of work on making the move invisible, as well as Fred Braue and I think Buckley.
Hope this helps,
