I have though, Lennart Green showed me a control very similar to this one using a Lateral Palm steal. I do believe he has done it in some of his older videos.
I have not seen you tutorial yet but from the performance I suspect it is very similar. I have been using a control much like this one for about 2 years.
I am curious to weather or not my tutorial/method is similar to the sleight you mentioned? i tried searching but could not find a sleight anywhere called the Lateral Palm Steal, i found Lennart Greens move called the Palm Steel but it was'nt the same move.
