Superman help

Hey all, I’m struggling with the last pop on Superman. Any helpful advice would be great. (I feel as though the triangle at the end isn’t very big. I use my thumb to pull the bottom string back as much as possible, but having trouble popping through the triangle.)

I find it helpfull to swing the yoyo to the other side right before popping it back through the triangle. this helps opening up the triangle and makes it fluent.

Hope this helps
