3K is Honoka's best move in my honest opinion so if you have the stun I'd for sure look for an opportunity to use it. It opens up the mix-game so much and causes a force-guess into what she is going to do. Just don't get too predictable with it. I, too, like it after 6T once you got the read that they are either going to mash or hold some other direction. Only use 2P+K46P in juggles. It isn't good enough to bother using outside. There is no mixup, so at a higher level people will hold you without a care. Using it after a force tech is somewhat okay too, but usually there are better options. It has nice unholdables and force techs from the wall though after a wallsplat so it has that use.
