Kung Lao's ex spin beats every option after 114, and he can just wait to see if you try to go into the clones. Even if you couldn't react and you try to 114, delay, then immedietely ex any of johhny's specials- ex spin beats it even in buzzsaw.
Mimic cancel into shadow kick or uppercut beat normal spin, but if he has meter, you can't safely go into mimics on block.
Lastly- both buzzsaw and tempest KL trades spin with shadow kick off of b34 mimic cancel.
So if you want to go into mimics on block, 114 is your best bet, but b34 is pretty damn safe too, as long as your opponent can't armor through the gaps.
