On the second time you pop the yo yo up i cant seem to land it in a double or nothing it always lands in a trapezes brother or a mount from Buddha’s revenge were the yo yo is in the middle.
Just make sure you don’t drop any strings and push into the last string.
you have to push into the string right after the pop and right underthe yoyo. Just take a breath before popping and then it will start to work out.
this tutorial helped me alot, hope it does the same for you
