Sorry if this was already found, but i was practicing mix ups with hazama in training (eww mix ups with hazama, garbage i know) but i found something pretty useful, if you RC the j214B# and do J.6D~D NEAR the corner (About 3/4 screen to the corner) if they tech roll backwards (really bad habit of most players) you should be on the other side of them and get a free cross up if their reactions are fast enough. If the don't tech roll backwards or neutral wake up you should be far enough to just being the zoning game again. With hazama's fast meter build the RC should mostly be free anyways.
Also since hazama has a shit ton of meter most of the time anybody else know how to use RC effectively for pressure or mix ups?
