Practice your throw.
Make it a lil’ bit faster.
Are you using a new yoyo, if yes then your bearing might need some breaking in.
But a good practice on the trick and throw is a big help.
what yoyo are you using? that happens with my dm because the gap is small, but it works fine with my yyf primo or peak. it have something to do with your gap.
I’m just suggesting of widening the gap but yeah practice throwing and the motions, with practice you could pretty much do it on yoyos with wide or narrow gaps.
I can do this on my FAST 201 stock, and pretty much any of my yoyo’s . I like to do it on loopers a lot, it makes people go, “WTF?!” The biggest thing that helped me when learning this was to make sure that my hands weren’t crooked, AND, when landing the yoyo backwards onto the strings, make sure your finger is as close as possible to the yoyo. So, needless to say, I disagree that it has anything to do with a gap size. just keep practicing it, you will get it
