If this is the perfect control, why the hell do you do a flourish while executing this. I'd use a misdirected pass over this anyday. Magic isn't about doing sleights that are 100% angle proof, its about fooling people.
Magic is not about fooling people at all. It is about entertaining. Why do you do a flourish? If laymen think that you shuffle cards while springing them, I think you could get away with a Cascade.
