Here is one trick I think you will actually like (though you probably already thought of it). Say you have D3 over 150% (or any character, but this works best on large-easy to hit-slow characters). Normally you need another ~30% to KO him. If you have a banana near by when you land a grab, then instead of throwing him back/forward and edge guardinig, throw D3 up and then pick up the nana, throw the banana up at D3 (requires prediction), and chase the nana with the Uair. You will score the KO early (160%). They can't escape the hit too: if they get hit by the banana they eat an Uair, if they dodge the banana you should be able to punish the air dodge with a Uair. Its win-win, it just requires prediction and timing. If you watch my matches versus Lain's D3 you see me landing a few uairs on him by just chucking nanas at him (and I think one scored a KO, IIRC).
