Crossing up Dee Jay is difficult. Boxer is hard also. Just takes practice.
I have taken games from the best Kens on XBL.
There are a couple of Ryus who I have NEVER beat. Ryu’s fireball speed and frequency allow him to totally lock her down, she cannot even walk forward because the fireballs are constantly pushing her across the screen.
I actually need to learn Dhalsim or Zangief. In SF2, I’ve never played a character that beats RyuKen, might be nice to try.
IMO, shotos are the hardest to cross up, followed by Dee Jay, Claw, and Boxer. The easiest are Gief, Sim, and Guile.
I actually prefer the Ryu fight over the Ken fight because I can SBF through the FBs better, but I do believe she has a harder time beating Ryu than she does Ken. Better FBs overall, better hurricane kick into throw/SRK mixup is better than what Ken has at closer range, which is basically an SRK. I’ve been able to stuff his FBs more than Ryu.
Lol, have you guys tried this one? If you’re up against a super reversal happy Ryu, you can do a meaty cl. mp and it will completely whiff on you, then you’re free to do whatever with all the recovery frames that he’s in once he misses.
Well…as far as Dee Jay, based on what I found, he can simply crouch and avoid your crossup attempt altogether. If you want to guarantee it hitting, make sure it’s meaty.
But, as far as both of them are concerned, I would highly encourage you to take a look at the hitbox on j.:lk:. Turn on the hitboxes in training mode and you can see that j.:lk:'s hitbox reaches far enough behind her that you can actually jump over your opponent and hit them in the back before you land (provided they’re not turning around because that may cause the move to whiff).
Like Milo said, it takes practice. Different hitboxes require different spacing and different timing to get the results you need. The farther behind the center of your character the hitbox reaches, the later you can wait to attack after you jump over them (which usually translates into a great cross-up).
I really should’ve rated cross-up difficulty on every character. 
That would’ve been too much work, though.
But, as far as Cammy is concerned, the easiest person to cross-up, is…without question, E. Honda. I can get j.:hp: to connect with no problem on him all day long. Blanka, Zangief, and T. Hawk get honorable mention. Difficult to cross-up? Dee Jay, for sure. Boxer and Claw aren’t as difficult if, again, you use the right cross-up (j.:lk: or j.:hp:) and get that spacing and timing down. Sagat can be tricky because of his height combined with his skinny width.
Okay so I’m going to tackle the crossups first and then the Ryu / Ken argument.
I personally like j. short for a crossup. Noriega I think you’re right that it feels floaty, but every jumping attack with the exception of j. mp feels floaty with Cammy in my opinion.
I haven’t seemed to have much difficulty crossing up Dee Jay or Boxer. The difficult thing about Boxer is you have to take into account how far back he leans when he blocks and you have to be patient before throwing it out or you won’t get to link when you hit the ground and then you’re in big time trouble.
Blanka has great hitboxes to cross up except I always seem to get reversaled… like everytime. Even against Blanka’s I don’t think are very good and to be honest, I don’t feel like Cammy NEEDS to cross up Blanka to win that matchup when j. mp is so strong…Zangief cross-up = lariat unless he misses or you hit it just right. T.Hawk… yeah you can cross him up all day but again, I’m not sure why you’d want to when you can play defense in this matchup and TK him out of just about EVERYTHING.
Crossing up E.Honda is easy but again, timing is everything or else you land and get Ochioed for your trouble.
Okay… Now I am clearly in the minority here but I still feel Ken is the tougher matchup for Cammy… Better DP with more range means ZERO jump in opportunity, better recovery means Ken can be ‘scrubbier’ with it and still fix his mistake whereas Ryu doesn’t have that same luxury. Yes, Ryu has a better fireball trap if he can push you in the corner, but I personally believe in the open field, Ken is going to have an easier time keeping you away. Ken can throw lp. Fireball and the only option is to jump over it or throw a hp backfist which = sweep every time. Certainly, I think the arguement as to which shoto jerk is tougher is an interesting one but I think we can all agree. they can both go to hell :lol:
Hahaha, yes. I guess I’m more comfortable facing Ryu because I’ve beaten good ones, but I find myself losing to scrub Ken’s sometimes. It happens.
EDIT: In light of the fact that its so hard to cross Dee-Jay, I argue that he and Guile are tied for 2nd worst matchup.
Agreed?
Nope… Guile is worse than Dee Jay in my opinion. Better turtling options and while Dee Jay may be a combo maniac and his cross up options are better, I’d rather FIGHT Dee Jay than Guile because Dee Jay would rather FIGHT than Guile. Guile should Turtle up and Make Cammy break through, Dee Jay doesn’t necessarily want to do that so you know I love ya man but I have to kindly disagree with that assessment. I’d rather fight Afro’s Dee Jay than Mars’ Guile… I have a higher winning percentage against Afro than Mars in that situation… true story.
It’s her jump arc, folks. Her jump is floaty, so naturally, her jumping attacks will be floaty.
BINGO!!! The man hit it on the head! It’s a timing thing. You have to be able to adjust your timing for different opponents.
Lemme help you out here.
One thing that I quickly learned on this forum is that there are some characters that you simply do not try to crossup. Blanka is one of them. His Vertical Ball is a ZERO STARTUP FRAME attack. It hits on the first frame. You cannot safe jump him…ever. Ken would be another person thanks to his zero startup frame Fierce DP.
And he’d be the third person. It’s a bit harder for him to consistently reversal, though, since you can’t Negative Edge the Lariat, so he’s worth at least trying it on. Make your opponent convince you that he can reversal Lariat consistently.
Heh heh heh…
I would cross him up for the time bonus I get for K.O.'ing him after I land her TOD. Given that he really has nothing to counter a cross-up from her, that’s a green light to me. If he blocks, push him back out and play defense. I guess the rushdown player in me says that they can’t knock you out if they’re knocked out.
IMHO, Honda is not just “easy”…he’s the easiest person to cross-up. The ideal cross-up target is short, but wide. If that ain’t Honda, I don’t know who it is. It’s very hard to mistime a cross-up on him. It’s almost too easy. Almost.
The fact that Guile recovers so fast from his Boom and his Flash Kick is so great make him ridiculously hard to get into. Believe it or not, I find his cr. mk more annoying than any of Dee Jay’s high priority normals since it has such long range.
Man… I don’t know why we’re not friends… Why are we not friends? You ARE awesome :tup:
Honda is a bitch though. All good Honda’s will try to headbutt a cross attempt, and jumping in with mp will get you Ochio’ed. Also, why does it feel like Balrog and Dee-Jay can literally walk away from a cross-up? Its like they can move before they even get up.
We are…just not in the XBox Live sense 'cause I’m not subscribed. 
One day…
But…since the Headbutt doesn’t hit on the first frame, you are safe to block it. Even better, if you block it while you’re both that close…AFAIR…he’s actually vulnerable to a point-blank range combo. (He actually gets pushed into you while you block both hitting animations of the Headbutt.) If he blocks, yeah…beware the Ochio if you don’t keep those links tight.
Dee Jay and Boxer…yeah…truth.
Cammy can actually be safe from the Honda headbutts if she crosses up in a certain way. The headbutt will just whiff, then Cammy can punish it with a drill or something. I’m not really sure how it’s done, but I think it involves using her jumping short and crossing up really deep behind Honda.
Its quite weird. Some Honda’s I faced could headbutt me as I was initiating a cross-up, but sometimes it worked. With you, Thelo, you saw how I was able to cross-up almost all the time. I think you’re right: Cammy has to cross Honda quite deep for it to work.
If I play this one Honda player that I know, he will headbutt me every time, 100% accuracy if I try to cross him up from knockdown. How is this possible??
You’re jumping too late.
If I jump any earlier, he’ll be free to just walk away and grab me once I land. Any later, and well…I don’t hit him.
Also, I’ve been reading that you can use Cannon Drill pressure strings (cr. mk, cannon drill, repeat) on Honda, but I find this to be untrue since his headbutt will either trade unfavorably or stuff the Cannon Drill. Anyone have any luck with this?
As with any character, it can be countered if too predictable. Its easier for Honda’s too since they’re already charging DB, as oppose to players like Ken having to react immediately. As for the cross-up: try to positing yourself in the middle of Honda when you land the lk, and make sure you do it late.
You know about safe jumps, though, right? Honda’s Sumo Headbutt has 8 startup frames for :lp:, 9 startup frames for :mp:, and 5 startup frames for :hp:. So, you have, at the least, a 5-9 frame window in which to jump in with an attack, land, and react to whether or not he’s Headbutting by blocking. If he’s silly enough to try a Sumo Splash to escape, that has far worse startup. So, as long as you time your jumping attack to hit within the first four frames of him getting up, you have yourself a “safe jump” attempt, my friend.
Don’t worry so much about hitting him as you should about not getting hit. The better players can counter and/or block and counter cross-ups in their sleep. You should be more concerned with making it look like you can’t be hit. If you can get them to think that, you can begin to play with the Honda player. And, given that this is Cammy we’re talking about, you need every advantage you can give yourself against Honda.
