I've put in a couple of days of trying, on and off as patience will allow... I cannot seem to get the ex ball (cancel) into dash jn1 to connect. It seems like no matter how feverishly I try, I can't cancel the ball soon enough. The doubletap down has to come after the first hit of the ball in the combo:
112, kano cancel, dash, jn1, run cancel, 32, 112, command grab.
I can get the second half pretty reliably, or at least reliably enough that I feel I'm making progress with muscle memory over time. I just hit the brick wall of the ball cancel into dash jn1 and it's getting frustrating... is there anything special to the timing?
