2kneeornot2knee: It depends on your opponent's char. Vs. floaties spaced or fading nairs are good, but if you misspace you will get shieldgrabbed or cc'd and *****. This works great against spacies too, but their nair beats yours. Vs. spacies it is important to observe how they approach. Fh nair poops on falcon nair, but if you instant uair under them it's super good. Platform movement helps to mix things up and at midlevel play it's awesome. Knee can beat some careless stuff too. And possibly the most important could be run up, sheild or dash back. Vs floaties it can force an attack that hits your sheild for you to punish. Vs spacies you can get a dd grab which is mad good too.
My boy shriek: dthrow knee, uthrow knee/uairs/ when he reaches for the bomb rush him. You can hardly ever ledgehog so jua
st hitting him on his way down is your best bet.
