I meant crouch confirms later on, when it becomes 5C -> 2C -> 6C. Things like 5B -> 6A you kind of have to guess, it's not easy to crouch confirm that early in. j.4D~A is kind of hard to react to afterwards if blocked, so I usually do that. Then depending on how that hits, I go on from there. After that it's your usual standing/crouching combo options.
And yeah, CH 6C -> 5D~B -> 5C -> stuff is the easy confirm I use there. It's not optimal, but it's still 4k. There's a lot of higher damage variants, but that is pretty consistent.
