Alright, I agree with Goth that this discussion is getting off topic and is going to turn into an online fight. So please fellas, just chill out. I think that, Rich, you are misunderstanding what S.G is saying. He is saying that(and correct me if I am wrong), yes, you do not need to have a spectator sign a card, but it enhances the trick on so many levels. If you were to do a simple ACR without a signed card, it would not be as good as an ACR with a signed card. And there are many other effects that go better with signed cards. But the reason we have spectators sign the card is because then they know, 100% this card is their card.
I get where you are coming from, saying that we should have smooth handling with our cards and all that. And I absolutely agree with you on that, no doubt about it. But we should have smooth handling with our cards rather or not the damn thing is signed or not. And if our handling for that trick is not best to our abilities, then we should not be performing that trick at that time. We should be standing in front of a mirror and practicing. In all reality, its up to you if you want the spectator to sign it or not. I personally have them sign it most of the time.
Now I am sorry, Sam, for getting off discussion. I just had to "try" to straighten that out.
I prefer the circle back, but its ultimately your choice in what you want. And yes, you can see signatures on the back.
But I as a performer prefer Bikes
