Illegal Eagle worked with me on this one. He showed me that it's def. easier to do when you're 1/4 from either side of the screen. Not right against the side, but about a 1/4 away. I've also found that it's just not a combo I would use in competative games. It's difficult to set up, it's difficult to do, and leaves you very open if you miss. If you have the chance just use the pop up, jk,tp, spear, 3 hit pop up, run jab, jk, air throw(or remove the run jab if you need to).
