1.5 mount rejection

I want to hear how you yourself do this trick. The position of the TH arm, pointing direction of TH thumb and index before the pop, movement direction and height of the yoyo popping up, wrist movement (if any), and so on. HD and slowmo videos are greatly appreciated.
I already have all the youtube videos i could find on this subject

R u talking about the chris chia one?

Yes, show us how you do the trick yourself.
