All of these are corner-only. I got j.SK -> j.FK to connect once, but it’s hard.
Dash jumps help somewhat. These were done to characters coming in from having a partner being snapped out.
They are all either Jumping JabxxStrong or Jabxx Forward or Jab xxu+Forward.
“*” is the point at which their guard is broken.
J.JP, * j.SP/FK xx Shinkuu Hadouken (27 points of damage, AKA crappy)
^ Launch into fireball into Shinkuu Hadouken (68)
^ Shin Shoryuken (82. I think this only works with Strong?)
J.JP, j.SP * c.JP, s.SP Shinkuu Tatsumaki (52)
^ c.JP xx JP Hadouken xx Shin Shoryuken (94, )
^ c.JP xx s.SP xx S.RK xx tiger knee Shinkuu Hadouken (66)
^ c.JP xx s.SP xx s.FP xx Roundhouse Hurricane Kick (53. optional Shinkuu -> DHC. You can omit the s.SP for lighter characters))
^ s.JP, S.FP xx Shin Shoryuken (worked on Ryu but not Cable or Sent during testing, so there must be weight issues)
For the other 2 shotos you can GB into the corner infinite: j.JP, * hurricane kick, (j.JPxx SP xx Hurricane Kick) And then launch after damage scaling, or Shinryuuken with Ken or whatever…you can get it up to many, many hits, however (hurricane kick is a special move, and thus doesn’t really add to the un-dizzy meter). Since I was messing around with other characters, you can do J.JP * J.FK xx whatever with Charlie (s.JP into launch, or Somersault Justice, or whatever).
