Hey now, the guy is just looking for a lil help. It's a question thread, it's really not that big of a deal.
Anyways, I've practiced retreated fairs a lot. I use the C-stick, for both fairs. You need very fast fingers to do this though, so there's your warning. At first you will notice that your 2nd fair isn't coming out, and you're going to really focus on getting the 2nd fair out. However, don't be fooled. I can almost guarantee that the reason your 2nd fair is not coming out, is becuase you are not getting your first fair out quick enough. The trick is to get the first fair out as you are rising, not falling. This is hard to do, because you need to move your finger from the jump button to the c-stick very quickly, which can be a pain. Another thing that may hinder your 2nd fair from coming out at all, is that your timing may be off. Practice memorizing the lag time from an auto cancelled fair (meaning when the lag ends from the fair while you are still in the air, or at least I think) and then press the c-stick for the 2nd fair. If you press the c-stick while you are still lagging from the first fair, the game won't register it.
Now that's some advice.
