Thanks for clearing that up Lunaris, I was referring to when Hazama was in the corner, not his opponent, so I was a little confused about the "dash under and crossup" comment. Just a misunderstanding I guess.
I agree with you about using it with 100 meter with or without FC. It's certainly the highest damage option when your meter is full.
Yeah, I'm still having a lot of trouble mastering the 6D->A x N, and following up with 623D. I try moving back a bit, but you can't be too far back, or it won't hit them if they're low. And whenever I hit them with Jayoku Houtenjin, they go flying forwards. As a result, Hazama's "icon" starts moving backwards... This makes it more difficult to adjust myself to the correct distance. If that makes any sense to you guys, haha.
I've noticed that sometimes the opponent flies forwards and up, while at others they just go up. Or less forwards, I wonder what causes that. Regardless, I'll keep training and eventually figure it out.
