Why would a pass use a duplicate?
Its not dirty at all and shouldve been one of the first passes to learn.
A great place to reference it is in Bill tarr's now you see it,now you dont.Along with other very useful sleights.
isn't that the same pass that he used on indecent???
anyways i use a pass thats a variation of the original pass i just perform it and a different offbeat than most and plus people can be burning your hands like crazy fully surrounded and still won't see a thing....i do it alot....
