No, do not stay in the air all the time, Tao beats you in the air, choose your moments, if you can land a 5A 6B then tiger knee a cloud, seriously, choose your moments, Tao's J.C and Drive beats you in the air, and you'll have to choreograph your attacks too far in advance to beat her--her main priority is her speed, which places them as better air attacks, if you're gonna be in the air, J.6C your ass off, if you can't catch her and she can't catch you, then that's good for you.
When the curse is on, zone. I almost always advise against it, but being in Tao's face is about as safe as being in Tager's face while on the ground. If you can find a combo setup that starts from long range, do it, Tao's speed seriously limits your options and good Taos can react to your every move. Wait for her to approach, learn her strings and punish them, then jump/bell, try your best to not get hit for the sake of keeping cloud/bell out, it does great pressure if you can limit her options, if you get the anti air cloud then jump to your heart's content. If you get the homing cloud, then make Tao come to you, and try to barrier block her into it, if she tries to cross you up with her dive, then jump. If you get the cloud shield, then again, wait for her to approach.
If she decides to projectile spam, well they are slow enough to avoid them, duck or jump to your discretion.
That's about all I know.
