Vs Cammy, lamo any time she does a cannon drill punish with rising jag, crossing her up is pointless. Only use jag kick if she jumps, cause she can punish with cannon spike easy.
Vs Chun, Her Jumping FP beats out like everything ive tried sept jag kick at a safe distance, also rising jag beats it out. Try not to jump to much since she can jump FP into ultra 2. Jag kick beats out almost everything she has if you get the distance right. EX Rising jag can of course go through anything she has also. Try to stay on the ground vs Chun jag tooth is pointless unless she gets her self in the corner and then you can EX jag tooth into ultra2
