I've been having a good bit of trouble landing the fair/bair. It's so much harder to time than it was in melee. The thing is, if you miss it, a lot of the time you'll get slapped around for having tried it. So my thought is...is it even worth doing it? I mean, it's **** satisfying, but it seems like one of those advanced techniques you do just to look cool but aren't actually at all effective.
Here is the truth:
#1 B-Air is Zeldas' best killing move
#2 F-Air is Zelda's second best killing move
This applies to both heavyweights and to lightweights.
So... YES it is worth it to learn these.
Hopefully with these two facts in mind, you should agree that it's worth it, right?
If you're not very good, then start off with the bigger characters.
Don't attempt this on someone like metaknight yet.. he is small and fast.
If you ever fight a snake, YES GOD YES use them. He is big and heavy and tall.
Snake is heavier than a sack of bricks, and falls just as quickly, so good luck trying to kill him vertically. You need the kicks to send him off sideways instead.
