well I agree that it sounds cheezy if you "XTREME this and XTREME that" but, what if in the patter, with the magic tricks, they say "ohhhh" when you do a fan or spread and ask more about it. you say "that's called card manipulation" and they say "i'd like to see some more"...
It's not the way it's being said, I was making a point about the simple use of it. It's an old marketing technique that, in my opinion, is simply overused, I think just plain "Card Manipulation" is fine.
then you say, well there's a type called extreme card manipulation... and start going 'Bananas' giant fan, double armspread, upside-down spring etc. i think they might appreciate the "extreme" modifier in that context?
I can't say for sure that it won't be met with similar thoughts that I described above, this is why I'm going to do the tests.
case in point - richard has used "cardistry" in speeches before and he said it was well recieved in that context, however, many forum members say they get laughed at when they use the word.
Like you said:
... if you don't like the term, it's definitely going to affect your ability to sell it.
