Just a trick I was just fooling around with.
Here’s how you do it.
1:Start in a Trapeze&his brother.
2:Do a Bro slack.
3:Here’s the tricky part, after you catch the slack swinging around, swing the string backwards as well as the yoyo. Catch the slack BEFORE the yoyo on the string, then land the yoyo on the bottom string. Bringing you to an Under mount. If all of this is done smoothly, it sure can be a crowd pleaser.
