I get asked every once in awhile about this stuff, so using copy pasta magic in paint and some free time I decided to list down the various strings that I use to go into j.BB tech punish setups so you never have to airthrow again, or at least less often. It's possible to go from anywhere on the screen using the correct string. These all assume you are facing the right corner and will bring the opponent there at an appropriate distance to catch them with 5A 2C tech punish.
If you don't know about the j.BB setup you can find more about it in Ikusat's Hisui video.

It should all be fairly accurate but some of it may vary slightly (using a different ground string without as much pushback, for example).
12A 2B 5C(2hits) 2C 6C j.C airdash j.B dj.ACBB
Covers about half the screen. I often delay the first j.B in this string to push them further and gain better height spacing. The doublejump needs to be neutral (input with 8 instead of 9).
2A 2B 2C 5C(2hits) 6C j.BC dj.CBB
Works from around the 1 on the map to the corner. Again, neutral doublejump. I usually prefer the first string as it often offers a better height, especially on some characters that can be harder to punish, but this can work too.
22A 2B 2C 5C(2hits) j.BC dj.CBB
For when you're just passed the middle. Input the first jump neutral if you're really close to the center and forward if you're a little further away from it.
32A 2B 5C(2hits) 2C 6C j.C airdash j.BB
Kinda hard to catch forward techs with this one but if they tech neutral or don't tech it does the job for that range. This could also work from position 2 with a neutral jump but the other string easily deals more damage.
42A 2B 5C(2hits) 2C 6C j.CB dj.AC airdash j.BB
It's considerably harder to tech punish off this one when you land as the timing seems to be more strict, but if you want to go from full screen this will carry them all the way to the other corner with you right in position to catch them. This can also be used after catching a forward tech (5A 2C 6C j.CB dj.AC airdash j.BB).
