it took me acouple weeks to get the feeling. When i first learned i justc oulden't get it. I wasn't bouncing it too much and would do bounce wait, bounce bounce, DANG!
Do big up and down motions. Just keep practicing. I practiced by doing putting the string over my nonthrow hand and bobbed my throwhand back and forth and the yoyo would do the same. So i tried it on the boingy boing and worked. But it was still sloppy.
I practiced and i got it perfect.
Practice makes perfect. Am i right?
