oh thanks for clearing that up, anyway
boomerang works for spacing
jabs work for spacing
bombs work(sorta)
ect
Ok ill make boomerang my example since its so easy to use. When you Zair theres always the chance they guy your facing dodges it or shields it leaving you vulnerable, though for a short amount of time, now why bother with this when its not even that strong, boomerang is around the same % level and its alot safer to use and yes you can still grab them or jab them or w/e you feel like (unless your doing it from a distance, though this still offers time to take out a bomb)
Well........I can't really critique your first 3 lines because, they are correct. The boomerang, jabs, and to an extent, bombs are good for spacing.
Let's break down that example you gave. I just wanna clear up one thing. When I say use the zair for spacing, I don't mean
only use it for spacing. Mixing it up with, as you said, boomerangs, bombs, jabs and such are the basics of how to space with Link. So if you thought that I'm trying to give you the notion of using zair spacing and zair alone, it's not what I meant.
Anyways.......
When you zair, it's relatively easy to hit the guy with it since there's 2 hits that occur. If the second connects, there's like....0.01% chance the guy will be able to punish you. The zair auto-cancels. That means there's little to no landing lag. This is another plus about it, and another reason why you're less likely to get punished for using it.
Now, should they spot dodge, the spot dodge can't last long enough to avoid both hits. If they roll, your landing lag is so minimal that you can punish them if they're behind you, or if they roll away, you can (as you said) throw a boomerang.
Also, Link does not have to keep his momentum in a zair. If you use a zair with your DI towards the opponent (like an aggressive attack), and they shield, you can still "switch" directions in midair and, when you land, you'll back away (due to Link's lack of traction when he lands - i.e. the craq walk). So...you can make an aggressive zair into a defensive zair, to an extent.
Also, not all attacks are used for their strength. I know I said not to use examples that aren't Link, but the best examples I have are for Snake and Ike. Both of their fsmashes are very, VERY powerful. Yet, Snake users and Ike users don't tend to use them very much because they are so risky. Relating to Link, the zair is in fact, a rather safe move to use. It may not do much damage, but heck yes it's effective.
Also, if an opponent is within range to use a zair, sometimes it's not the best idea to pull a boomerang. Link has a slight lag (he pulls his arm back) when throwing the boomerang. You can be punished during this time (it's happened to me before, heck it's even happened to Legan before).
Now, if I was unclear about anything, lemme know. I'll do my best to explain it again.
