Well, i feel that i, personally don't like performing this type of repeated trick, where the same thing keeps happening but other people tend to love it?
I use the classic force via Paul Green's Classic force video, and ill tell you a story about first using it..
I was in a bar with my dad in London, the kind where kidz are allowed (im 15), and his mates heard that i am a performer (not a magician cus i only perform tricks and sleight of hand, not magic), so they asked me to do tricks for them.
I was stuck as i had no props but i am a sleight man so i done some coin stuff and lots of impromptu stuff.
Anyway.. to get to the point..
I shwed this guy an ambitious card routine (Daryl's kinda material) and he looked and just said it was amazing etc, but he got bored after the cardkept jumping to the top, and he + his friends told me they like card tricks that have a flashy, quick and amazing appearance, so i decided to try out my classic force, especially when he told me of this man once asking him to pick a card and the man named it straight away etc, so i successfully performed the classic force, named his card, and this guy went wild, he just started shouting abuse, and ran around the bar, i then offered to repeat the effect, and got him to pick a different card, but it was the same card, and i managed to keep this up, even with him choosing the top card.
The point of that is, that, the trick is funny, wierd, quick (not long and boring), easy to understand, and flashy in a way, although i dont even enjoy performing it.
I think this should be done more as a joke, and not an actual effect, because alot of forces can easily go wrong, especially the classic force, if you get the wrong spectators.
That is my opinion, although i would keep forces to when i 'need' them, in most performances, if you know what i mean.
