Double stick DI and using it against Fox

This post might be kind of long, but I heavily recommend you read it, as it will likely benefit your play.
Alright so I've been doing some testing lately and I think it's about time I make a post on double stick DI out of platform combos, specifically the MU that it's surprisingly underutilized in, against Fox McCloud.

Many top players and technical players already know that double stick DI out of Marth platform combos is extremely important, for example, here is a gif of Falco double stick DIing out of Marth's utilt techchase on platforms (excuse the tags):

Okay, now it's time I go over its utility against the Fox, and how you can turn a poor situation into an advantageous one.
To double stick DI Fox's uair, you simply hold your control stick horizontally off the platform you're on while being near the ledge, to get your DI, and ASDI down by holding your Cstick down.
Captain Falcon can double stick DI Fox's 2nd hit uair to 32%, however, it will be different depending on your character.
If they techchase you with both hits of uair, you have 2 options:
1. ASDI down the first hit of uair then double stick DI the 2nd.
2. SDI out of the first hit uair, escaping the combo completely.
Here is a gif of number 1:

In this gif, Falcon ASDIs down the first hit of uair, then double stick DIs to escape completely, also giving him the opportunity to uair Fox in the process.

However, I think you should instead SDI the first hit of uair which would then force the Fox to 2nd hit only you, extending the range in which you can perform this technique as you don't have to worry about the 5% damage from the 1st hit of uair.
Here is a gif showing double stick DI on the 2nd hit of uair only:

As you can see, the percent range is a bit higher due to not having to worry about 1st hit uair, and Falcon still got the uair afterwards, turning a bad situation into a good one.

I hope you all learned something from this post, double stick DI is a really broken mechanic and I hope I've shown that if utilized properly, can be devastating to a Fox player.
