I did some labbing, if you're hitting air to ground j.S or H can combo into 5K. Then go into what you like. 5K into c.S 2D works, you can omit the c.S too and go straight into 2D. You can also go into 5H pogo going my way but it doesn't work at longer ranges.
5K has quite a lot of range, you can go directly into other stuff but it may whiff.
