Many people know this change. First off Dan and Dave started this change, and it's original change is G.O.A.T change. After, ineski and other people have found there own methods for the change. There is rumor that Dan and Dave will publish it in the fourth disc of the trilogy named AndThenSome, but were not certain.
I apologize for bringing up an old thread, but I have gotten a bunch of messages about this recently, and after a Google search I was lead here.
Yes many people know this change, although the handling differs, the actual change is very similar.
This isnt something that was just copied from a performance. I developed my own handling after not being satisfied with the ending of an effect by a young magician named Tyler Wilson. I think it was in Vancouver, or maybe TSD Atlanta in 05 or 06, I cant remember.
I dont know what the original name was, nor who came up with it, but I can assure you it wasnt the Bucks and it wasnt called GOAT change. For me it was a more visual way of ending another effect.
