I recently found this and thought it was interesting. I’m sure it’s been posted but wanting to bring it back up. I’m particularly interesting in 1/2 A. Does anyone have any videos of it?
Try and find Josh Yee’s youtube account. I bellieve there is at least one video dedicated to that style even though its one trick in it.
Incredibly hard style of yoyoing.
the hardest trick i landed on .5A is plastic whip
