Yes very strong as it is often very hands off. Many times when doing sleight of hand your audience may not know specifically what you are doing but they can sense you are doing something tricky. Here with the semi automatic effects it is usually not hard to do and you can be away from the props. As an example, check out DVD 2 of the Woody Aragon set and you will find some killer semi automatic magic. Obviously top guys like Dani DaOrtiz, Woody Aragon, Michael Weber, Simon Aronson, Jim Steinmeyer, Bob Neale, etc. understand and use this type of magic. Check out:
