hey! I just tried this for the first time, and I didn’t seem to have a problem but there are things to keep in mind, I’ll try my best to explain
1- when you’re trying to wrap the string around your index on the OFF hand (0:20 in the video) it goes INSIDE the triangle you’ve formed and onto the string, not just around your index and onto the string like a normal double or nothing. watch the video carefully if i didn’t explain properly lol
2- make sure you drop the strings off your yoyo hand first, and then the string on your THUMB from your left hand
3- green triangles can be a little tricky, but this isn’t exactly a green triangle, it looks like one (so i guess it is LOL) but make sure you’re popping the yoyo out TOWARDS you! so not to the front of the string but to the back.
4- after you dismount, there might be a little “crumble” in the string which u just need to tug on, for it to go away, but not a knot.
I hope this helps! so keep practicing and good luck LANDING IT
