I've recently been experimenting with using the first part of up-air to combo. If you don't know, the there are two kicks when performing an up-air. The 1st kick has a small, set knockback. And the 2nd is obviously the stronger, more powerful attack. I use it during mid to high percents, and usually from a fast falled full or double jump. Now because of the set knock back, i find comboing out of this to be very easy. If I land and their behind me, I usually up-tilt. If i land and their in front of me, well, I usually either look for a way to combo or simply up-smash them. Of course you could simply crouch cancel this or whatever, but like all moves it shouldn't be abused. I am curious as to what everybody's thoughts on this technique are and would like input from ppl, especially those who might already use this.
