I dont know Any whatsoever… All I know is when you throw the slack, what are some tricks of that? thanks! For some reason, also, after I throw the slack my yoyo (supernova, so it should spin long) loses a lot of spin, why? Thanks!
Have you seen the bro slack to ninja vanish? After catching the slack, rotate your NTH around while letting go with your TH and land the ninja vanish.
