Hmm wes I remember seeing you do some weird spaz grab thing at the last tourny was this it? If so it looks weird as hell lol.
What's going on there is he DA dashes (pivots) into a neutral stance and then fsmashes whenever he wants to.
Doint a pivoted neutral stance has multiple advantages:
1) you can choose when to do the fsmash. You can do it right away (equivalent to doing, say, a dash dance and timing a forward smash, for example, on that one frame window you have on the dash dance turn around). You can do it on frame 2, or frame 3, etc. You can choose. It gives you more control
2) If you have pivoted neutral stances mastered, you'll find you can pivot moves much more consistently than trying to do it the "old" way by timing it on that 1 frame window.
The problem is, pivoting neutral stances is kind of hard to do. The only people I've seen who have mastered this are wes and Mr. C
Hmm, actually on second thought I just noticed you said he was doing a weird spaz "grab," so I might be wrong on my description. But, unfortunately I already wrote it out so I'm just going to keep my original post. It might be the right description of what you're referring to.
