Although there may be too much ending lag with the grounded lasers, so by the time you've finished shooting the last laser and IAP'ed, your opponent might be able to get-up, roll, etc.
Oh and J4pu, I tried staling the down throw and that didn't work. Instead I did a dthrow on wolf, and my friend DI'ed AWAY from falco. I think that this is the only way he can get the jab on certain characters (this includes toon link and a couple others that I tested).
Can anyone confirm the fact that certain characters MUST DI AWAY from falco in order for the jab to connect?
