First off Kevin will release a dvd this year with the flourish. I think it's a virts dvd. Second you have no right to force someone to make a tutorial. Kevin already said that he will make a tutorial, just not for free.
yeah... when i talked to Kev he told me that he would be putting this move on the Virtuoso DVD so chances are he is NOT going to be making a tutorial for this before then. The Virt DVD will hopefully start recording when Kev goes back to Singapore to meet with the other members of Virtuoso later on this year... but that is not to say that the editing and production of said dvd will be done at the same time.
