I feel that round start upback, assist call, delayed grab with peacock/band is pretty much safe from anything parasoul could try? unless BE gets beat out by something, which could totally happen, but in that case you probably chicken blocked j.lp so you have the advantage after landing and a 6f jab to throw out.
		
		
	 
I can give this a shot, thanks.
	
		
	
	
		
		
			Also, Bigband's j.lk is 7f while parasoul's j.lp is 8f, you just did it later in that case. BB's j.lk is the god normal.
		
		
	 
Skarmand touched on this too, it looks like the difference is he was doing his j.LP immediately after his jump whereas I was doing my j.LK a bit later than that. I should try to get in the habit of doing j.LK earlier. It's active for days so there's not really any reason not to.
	
		
	
	
		
		
			IDK if you've tested this and sorry if you have, but have you tried using air to air j.MP vs Para's buttons? Might be useful especially at round start spacing.
		
		
	 
ClaranceMage said the same thing (is this an AU thing?) but I have trouble getting my head around the idea of using the button like that. Are there particular points in the match that you can point to and say "push j.MP here"? I'm asking a lot I know but I think that's what I need in order to understand this, lol
@Skarmand I'm not gonna quote your whole post cause it's huge but thanks so much for all the advice, this is super helpful. In brief:
-I probably do need to Cymbals as Band more often in this matchup. It's sort of a weird mindset to get into, because Band has to work hard to get to half screen, then when I get there I'm supposed to stop moving forward and throw out pokes. It's tough to put on the brakes, when I'm in that mindset and I get that close I just want to jump and push j.LK. That's something I need to work on more.
-My Peacock assist doesn't really make Big Band stuff safe per se but it can make it weird to punish since there's a bomb on the screen. I usually call it a lot when Big Band is out, I don't know why I didn't this set (maybe I was scared of Peacock getting hit as an assist? Dunno). M A-Train with L Bomb assist is probably safe so I should do that more.
-You're also right I should play the team in the opposite order more often, I do that sometimes but then I'll go long stretches without doing it. It's only as of reading your post that I realize I'm in one of those long stretches right now, so it's time to put Big Band on point for a bit. 
-The problem with start of the round assist call vs Parasoul is that depending on what I do, dash up c.LK or dash up throw will blow it up. I've learned this from playing Fenster, and now I don't really try that opener against Parasoul. I think Caio's idea can work though.
-I'm not normally really trying to rush down when I go in with charged items, it's more that I want you to move backwards so that I don't corner myself. But again against Parasoul I probably should just use uncharged items more.
-For Robo if you don't want to deal with not knowing if j.HK will do the last hit or not, you can hold down forward to ensure you land before that hit comes out. It's less damage but more consistent. I had trouble with that too when I was learning Robo.
