overall a good video, athough I'm not to sure about the c defending setup, as the wall can give your opponents the space to walk out withou their controller having to smoke anything
this smoke is very inconsistent; this is happening to you because you throw too early when you jump and place your orb. you have to jump just shortly after you throw (and the placement of the orb can differ depending on the millisecond difference between your jump and throw). I think this may not be an ideal lineup in general though.
