four packet

I've been performing this trick lately, and I've been getting some pretty good reactions to it. However, I have to admit that I was never a big fan of this trick due to its complex mechanics, but after some adjustments, I think I've made it very easy to perform with any deck, under any condition...

there's this one flourish I really wanna learn, but I don't know what it's called it's driving me nuts, I don't know the name!
