Okay, I've pretty much got it down, but my question is, when I'm waveshining a character with less traction, like say a Marth (whom is my training partner/rival is, so I play against Marth alot), I know I need to walk/dash a bit afterwards, but I was watching this great fight
http://www.youtube.com/watch?v=NqQB55d-Tdw and @ ~1:57, Isai waveshines Marth but doesn't seem to dash afterwards, how does he cover the distance to grab him? Is it because he hit Marth in the air? And @ ~2:00 he waveshines him again withiout the dashing...?
