They're hard to find. Honestly I think GW is a character where mimicking people definitely doesn't work since he's a more mental/read based character. You have to be smart to use GW and make him non-linear. Even if Vinnie actually did use GW (
) you wouldnt learn much, you're not vinnie, vinnie is just really good and when he uses GW he applies the same **** he does for other characters. Alphicans has the most recent videos i would think. You may learn a few things by watching players like GIMR and UTDZac (his videos are older though, he retired)
But yeah you just have to figure out what works for you. You won't learn much outside of matchup specifics, you just have to play really smart. What matchups are you picking GW up for? I can give you strats and ideas but that's all they are.
