Since we were talking about it in the other thread, one way to use F23 safely during pressure is off of a ex low hat set-up. If you do ex low hat, and follow it with a run, you can time it so that the ex hat connects exactly between the first and second hit of f23 (trust me, it isn't as complicated as it sounds). So if your opponent tries to backdash, the ex low hat will hit (and the second hit of the string), and if he tries to armor, the combination of ex hat and the second hit of the string will beat his armor. Best part about is, since the low hat connects between hits, Kung Lao gets his hat back, which means you can cancel the string into another low hat.
