Awesome. Thanks for the help, Magnus. I totally never thought about the Rodeo Hold. I'll give that a shot. I've tried but always seemed to get stuffed. Maybe I'm hitting it at the wrong time. I appreciate all your suggestions.
Rodeo throw is a good tool to use, but I don't think it's all that useful on defense against fast characters. Unlike defensive holds, offensive holds don't come out instantly, and the faster characters have a surprisingly easy time knocking you out of the rodeo throw before the active frames for the hold start up. Also, Christie and Kasumi both have throw mixups in some of their strings so if you make a bad read against them with it, you'll be eating a good chunk of damage. You never know though. Throw it out every once and a while and see how your opponent reacts.
Defensively, I think your best options for dealing with speedy offense would most likely be 1p and 1k since they crush highs, and the sidestep if they're not using moves that track. 33P is also a good tool since it ducks under highs and rewards you with a launch, but it's unsafe and kinda slow so use with caution. 6P is good if you think they're gonna go low and like Magnus said it can lead to a lot if it hits. Tina's like Bass in the sense that faster characters tend to be her worst matchups since she has limited answers to their pressure outside of holds. You kind of just have to be patient and look for something that can be crushed, sidestepped, or throw punished like Magnus mentioned.
