The above hat trajectory is better the further you are away from the hat, so 21 doesn't do much for above trap at all, this is why i never used.the plan is to get a hkd using 21. ender that gives me the proper amount of space .. then the setups I posted above apply.
However, Away trap does, but its on the video the countless ways one can use away hat trap, it justs lets you down when you read a wakeup and block it.
Forward low trap does too, which is set up an opponent to either, delay the wakeup, block low or standing, if they block low and you hit them with F4, they will get kd further away passing the low hat trap again, which leave in perfect position for a oh/low mixup from a cross up which you can delay as much as you like to set up a very ambiguous low or a very ambiguous overhead, both safe on block and plus enough to apply pressure meterless or metered if they block it.
