thumb grind!

can someone give me some vids on how to do thumb grinds i was think of doing them

here are some good vids,
or this

you just simply put your thumb into the inner/outer grind ring. Your thumb should be in a slanted angle, try watching the vid to clear it upĀ  :wink:

Try tilting the yoyo, it helps.
