For better consistency at the beginning (before you get used to the timing) you can use easier version of this combo. From easy to hard list here :
cl:hp: xx Hado , fadc , HK Tatsu , fadc , cr:mp: xx LK Tatsu , sweep
cl:hp: xx Hado , fadc , HK Tatsu , fadc , cl:hp: xx LK Tatsu , sweep
cl:hp: xx Hado , fadc , cl:mk: xx HK Tatsu , fadc , cl:hp: xx LK Tatsu , sweep
cl:hp: xx Hado , fadc , cl:mp: xx HK Tatsu , fadc , cl:hp: xx LK Tatsu , sweep
Becareful with cl:mk: I use it because with :mp: I get overhead too much for the moment, but this :mk: whiff on a crouching Rose after an fadc. Maybe on some others but anyway.
And for the god of the hitconfirm, you have a 2 bars force stand combo too after a tiny hitconfirm. You can’t expect to hitconfirm with 2 crouch jabs because it’s highly char specific, so here is one that works on everyone (except Blanka ^^ ).
j.:hk: / :mk: , cr:lp: , cr:lp: xx HK Tatsu , fadc , enjoy
