Grind binds are my favorite. I made a video of some, here it is: http://instagram.com/p/rqkDQESdrg/?modal=true
First one:
Get into a plastic whip mount, put the yoyo in your hand, and bind. It will spin out when you’re done.
Second one:
Same as the first, just put it in a hat.
Third one:
Do a fingerspin, then whip the string into the gap.
Last one:
Hop the yoyo into a finger grind, push the string over it, and hop it up.
