Yeah the TK Loop is tough. I can't seem to manage it and i know Hazamas timing well enough for each of his moves. If your doing it exactly at you see it, after TK, the 5C is too slow to actually connect. Which screws it up for the rest of the loop if your unable to do even a single loop. Its a tough combo(s) to master.
As for the accidental Super Jump cancel, its just about the timing. Slightly delaying TK is what i found to be an effective method. Too fast and the motion isn't read right, forcing a Super Jump. Slight delay, accurate input, and your good. Just find the right motion. I practices for ages trying to perfect it. Just move to the opposite end of the screen in practice and keep TKing towards the opponent till you get the right motion. Then swap sides. Repeat. Then try it in combos to get used to the timing to avoid a Super Jump Cancel. After that, your set to practice the TK loop combos.
Would love to master Hazama. But i'm shit at BB. Good at practicing and that.
Good luck with the TK loops
