Wow. I predict lots of conversation. But its really over nothing significant. Use the best method available to you, within reason. It's common sense. Use the best presentation you can and don't bore people with stuff they don't know or care about.
It is as simple as that.
Do NOT worry about magicians. If you can fool 'em, great. But paying ANY attention to that portion in your audience always takes attention away from the real audience. The real audience is not made up of people who care about weather you use the dribble or riffle force. Of course, I am sure most magicians will agree with this assesment; but as Corinda highlighted, magician's have the inclination to be very hypocritical. I know personally, that I am often tempted to make improvements to a method which I know only a magician would appreciate. I think it is something to do with the whole ego situation amongst magicians, but its something which I reckon is probably fairly natural. BUT If you want to actually make an impact on your real audience, then you have to drop hypocracy and force yourself to act upon your reason. Derren did it. But remember Derren is just one exemplar.
I'll not make a habit of this, but seeing as its somehow still relevant, Stanislavski actually commented on this.
Now I will show you what should never happen onstage but which unfortunatley, almost always does with the vast majority of actors. I will show you what almost always occupies actors' attention when they are out there on stage- a ferocious critic.
