The fact that I train on my 3DS doesn't make it easier either..
Are the <-,-> inputs on a timing similar to a dash dance?
So a small update on this. I've found out that on the 3ds, pulling the stick backwards only slightly, like doing a Tilt attack and then immediately smashing it forwards, like doing a Smash attack makes the lagless FAir from ledge work 100% of the time for me (when done fast enough)
Also on a semi unrelated note, I've been trying a thing. At 0%, Short Hop, DAir, Fastfall, UTilt (or turnaround UTilt if you land behind your target), Jab1, Grab. It's not true and both DAir and UTilt can be teched but it's a 30% without the damage from the throw and followups, reaching 65% with DThrow, UAir, UAir, UpB and it looks cool, especially if you land behind your target.
You can also crouch cancel Jab1 to make this faster? IASA frames? I don't know enough about these..
