i totally gave up on the ex tatsu > jab reset, mainly because so many sakura players use this reset, too many that even my grandma does it.
All other higher level players, or players with experience already know how to deal with this setup and over 80% of sakura players would attack instead of bait after the jab, plus it’s actually extremely easy to see which side you r on.
Being a sakura player it just comes down to reading your opponent, and being read.
I wouldn’t recommend the ex tatsu > jab setup mainly because there are much more options that has advantage than this.
What i usually do after a ex tatsu is to front dash > early or late j.hp, the later you press your punch more chances are you will land behind them, and the harder for them to see, and if you can land this reset and u catch them not blocking the right way u can go for another same reset combo but this time land on the opposite side, you cant believe how many times i hv made comebacks with almost no hp with this combo. Depending on which character you are playing against, usually after 2 reset combos and one or few normal they will get stunned. using front dash > j.mp is also good since it looks like you will land behind but u will land in front.
But don’t rely heavily on reset combos as they will only work once or twice in higher level games.
I only do resets when I am lower health than my opponent and need to make a come back, otherwise, it’s far better to end your ex tatsu in otoshi x2 or (x3 with a safe jump afterwards) or sweep with different setups to maintain your momentum.
Lastly, one last piece of advice, and i do believe this is an essential key for higher end sakura players…
Do not abuse ex tatsu and learn to end your combo with srk, as ex tatsu will always lose one meter, srk will let you GAIN meter, meters are extremely important and its not meant to be wasted, for situations like getting out with ex.srk, and FADC. It will also make your opponent to think twice of what to do on your wake up, which can lead to your advantage if you can read them.
Another advantage of ending your combo with srk is that there are so many more setups you can do, such as safe jump j.hk > lk. tatsu to catch cr.techs, or j.hk > block strings / combos, or just bait reversals > punish, or just jump and cr.lk > whatever, or just empty jump throw
only use ex.tatsu to regain momentum or to make comebacks, or when you think your opponent can read you too well, otherwise stick to srk
just my 2 cents
