The way I look at it is that its not ever worth doing 11 on its own. 112 should always be thrown out as its simple to hit confirm into spin. If its blocked, they have to guess if you're going to stop at 112 or 1121. The options from there could be:
Stop string and throw
d3, 24 options
24 options
21 options
cross over
cross over and teleport mid jump if they like to AA
teleport~3 (can work against high hit box characters)
spin (If you know they will poke after 112)
The problem with b33 is that its start-up is 13 frames so can easily be interrupted. It will no doubt work online but probably not offline.
b3 is 11 frames, b33 is 13 frames, but you need to know the b3 startup which its all about. the problem with b3 is not the speed at all since 11 frames is hella fast, the problem is the range since you need to be almost right in peoples face for it to connect. It is a bit hard to hit confirm as well, the setup I use for b3 is after a succesful d3.
about the b33 spin, did you guys know that you dont have to hitconfirm it in the corner, you basically do b333 in the corner and if it actually hits you have more than enough time to get a spin in, and do a few sets of 1 1 1 into 24,1+2.
when an opponent is almost at the corner you can do b333 teleport 3(b333 sends opponend into the corner, teleport 3 will juggle) into spin 42 1+2.
24 is a very good string and people have to respect the follow up low hat or overhead so they keep blocking most of the time which allows you another set of 24 for chip. when they uppercut or poke you out of it you can use a risky spin after a blocked 24(imo a worthwhile guessing game, much like after a blocked low hat prepatch, will he spin or not?) against certain characters you want to play safer. in that case I would use 24, 212121 for chip.
IMO kung lao isnt about raw damage but about all the chip options he has, the spin people need to respect so much during situations where people can pressure you afther they blocked your attack, his mobility and in general safe pressure, this character is also the character that has access to ridiculous amounts of meter compared to the rest of the character roster.
sorry for the long post guys lol, its just a small part of things I found out about Kung lao in the last couple of weeks. and looking at the forums there is no real way to know whether this is known or not.
