On the contrary, it's easier for me to use whichever move fits the situation more. Even if you save fair, one stale hit, and it kills your potential killing with that move early anways, so it's best to use it whenever you feel like it works imo. Against sonic, it's easier to wall him with aerials than try to get a lucky fresh fair.
The second match was me playing around with him because he doesn't use snake, part of the reason why I didn't link it. Never use sing, because people can mash out of the first and second pulse before it ends. I used sing only because I could, basically =/
