Okay LOTS of confusion in this thread. No one reads my work. EVER.
Anyways, the dtilt DOES lock, but only around 100%. Once you lock with the dtilt, there's no tripping involved.
Ademisk, your PKT2 combo doesn't actually work as a combo. People can shield it. However, the combos in my video are generally inescapabl (maybe the hothead is, but that's it). You have to rise up high enough to not brainshock them.
Ness can combo into footstools VERY well, but they are mostly for GROUNDED footstools which DONT set up for the jab lock.
But Ness CAN combo into this. This is how you do it.
Use an attack that launches oppoentns up with little lag afterwards (dash attack, auto-cancelled uair, or dair). Then immediately jump and footstool the opponent. MAKE SURE ThE FOOTSTOOL IS A SHORT HOPPED FOOTSTOOL. Then fast fall and autocancel an fair. Inititate the jab lock. That's how you do it. TC's method does not work.
Oh, and lol Yuna arguing against Ness again
(waits for retaliation)
