I’m not sure if this is a known trick or not. I’ve never seen it and stumbled upon it myself.
The first time I do the mount it’s just the front string. Kind of a weird backwards Houdini mount. The second time the yo-yo hits both strings. Pop out towards yourself and do the flop. It’s kind of cool because when you drop the yo-yo it’s in position for a bind.
Let me know what you think.
