shffl dair -> shorthop/fullhop stuff is most likely quicker than this tbh Phenom.
EDIT: why the hell does SDM's Frame Data say "CAN'T" under L-canceled landlag for uair, nair, and bair?
You are right Strong Bad. Shffl dair to sh dair is much faster to full hop Dair to short hop dair (before landing on the floor).
Strong Bad it is not about speed always; this technique can create enough suspense in the air to allow a possible opening to follow it up with another aerial.
Example: In the video, it shows how I spike my friend DannyX(C.F. in the video) after I juggle him with the u-air and then spike him down with a D-air(must be done in beginning frames of the move;3-4 something like that.) and follow it up with a B-air I believe. My friend DannyX was perplexed in the timing(suspense) because of how slow the technique seemed that he did a get-up-attack to early and got punished for it.
Let's say he teched it and rolled. I would've teched chased him in the air and either have B-aired or F-aired him.
Just to say again, it is not always about speed and especially for a Game and Watch main.
Thanks for your input Strong Bad; I find this argument beneficial to my fellow Game and Watch peers so thanks man.
Also, on SDM's Frame Data it says "CAN'T" under L-canceled landlag for u-air, n-air, and b-air because you can't L-cancel those moves with Game and Watch. So as elvenarrow3000 suggested.
