I love that move usually when there's a huge gap between you and the opponent and you run towards them when they think you're doing 66K or 66PP while you're doing 66H+K
I hate that move. It feels like I'm -300 frames when I use it. I have enough time to go "Oh shit" before the animation goes through and I eat a low grab. xD
Ok for starters why are you using 2H+K that's is her worst low lol. 1P is horrible on netural hit & unusable on counter. 66H+K can be free walk and its easier af to see and react too(Even online)
2H+K I use at least once to condition my opponent to watch out for lows, it works in most matches I have. 1P i like because it knocks down if done twice on counter, and most opponents think you're gonna go for the P follow up or another high/mid, so it's good for tripping them up.
Another trick I like doing in a spacing situation is to hoshinpo, quickly h-cancel then follow with 1K during the very end of hoshinpo. I love how it throws some people off, it's almost like a pseudo follow up if you do it smoothly
