Thumb Grind to Triangle
Begin with a Spirit Bomb mount as in Spirit Bomb. Pop the yo-yo out the front of the Spirit Bomb mount. Hold onto the triangle with your non-throwhand.
Bring your throwhand down towads the yo-yo and guide your thumb into the inner groove. Let the yo-yo sit on your thumb and precess as you bring it towards the loop being held by your hand.
  As the yo-yo turns around towards the loop, make a small throwing motion towards the string to throw the yo-yo into the newly created triangle. It it needs to be straightened use the string to do so.
  Pop the yo-yo out of the triangle on the side closest to your body. Land the yo-yo back onto your string and return the yo-yo to your hand.
