Well, I have been holding neutral before performing the qcfx2 motion, but it doesn't work.
I am juggling the qcb+A after a qcf+D,D, so canceling the second hit won't work because the opponent bounces up high from the second hit.
I'd rather get the qcfx2 DM out instead, because the damage is so much better.
Can you try it and see whether it is possible?
Of a similar note is me trying to use Krizalid in MAX to cancel his dp+A/C to hcb+A/C, no matter what the qcf,hcb DM comes out instead.
