Good! I can't get everything, you know. About the bolded text, I actually went in to training and tested vs the entire cast sans kliff/justice. I tested it without delays for the most part. I'm sure there is a nicer way of saying this ;o It combos in your video because you delay HCL and let Sol partially recover and his head rises after the initial COUNTER, giving you the hit with HCL. It doesn't combo if you just did 5hs cancelled straight into HCL, which chances are you will do in a match because that normally combos. That is why I said it didn't combo.
5k JI 6p 2d for Ky, Robo ky, Johnny and maybe one or so other character. 5k JI 6p works on pretty much everyone else.
It has a blind spot in between I-no and the guitar laser. People can run through it as it's forming. It can be good as an oki when you couldn't get close enough for anything else. It catches backdashes too. 5s(far) vs heavy opponents can be linked to 5hs (which goes to TK HCL, IAD j.k j.s VCL, tk FB, jc j.s j.hs etc.) 5s(far) vs other opponents can be combo'd straight into j.s j.hs if in range, link 5k into HCL 6frc6 on some characters (millia for example), or straight into TK FB.
I've tried this. You're better off trying to block the unblockable. Why? Eddie usually will do the puddle unblockable (I'm guessing this is what you were referring to) with j.s for crossup/fake crossup or j.hs for its meaty properties. You're giving him a free air counter hit that can be confirmed into 6p into an air combo, land again, high jump combo that will take off a LOT of your life bar and build your stun anyways.
