Also the bnb combo that ends in med sbk seems more difficult after a low air lightning legs 
Thereās multiple things you can do to make it work. Youāre right, itās a spacing issue. You have to throw it from a further distance in order to gain more advantage and to be able to combo cr.mk afterwards.
This can be achieved in several ways:
- Space your jump-in so that youāre not directly next to the opponent. Like after a stun, dash up to the opponent, then take a tiny step back and then neutral jump and do your combo.
- Delay the b.hp after you hit a jump-in. This means you have to hit the jump-in late and really low to the ground so you have time to take a step back.
- Delay the EX kikoken after you hit with b.hp. Donāt cancel it instantly, cancel it later.
- vskill jump-in almost always works because of the floaty jump. Like after a stun, you can dash up to the opponent and then dash backwards twice. Then do your jump-in combo (I suggest using j.hp, itās very consistent when you come out of vskill)
After EX Kikoken, I usually just go for EX Hyakuretsukyaku or, if Iām feeling meter-thrifty, a simple LK sbk. Itās not the best, but it still looks cool (lol). F+mp xx V-Trigger or even st hp xx V-Trigger are also good after a correctly spaced EX Kikoken, but itās sort of difficult. Some of Sakoās EX Kikoken combos, especially in the corner, are really inspiring, so I think Iāll try to learn those as well. EX Kikoken, cr mk is just really specific, so it might end up being thrown into the ācanāt do it so whateverā box with the cr lp, st mp xx Kikoken combos.
This cr.mk xx SBK is a very difficult combo (I thought SF5 was getting criticized for having easy execution? lolā¦)
As others have mentioned, you need to press st.mp then immediately hold down, cr.lmk and cancel the cr.mk into u.mk very late. Itās not easy to do, and youāll need to practice so much in order not to drop it in a match, but I think itās worth it. 215 damage and 380 stun is quite substantial for a meterless combo that converts off a cr.lp. The wall carry is also very good.
Thereās no real trick to it, no real gimmick to make it easier than it is - just have to practice, practice, practice. I still canāt perform it all the time, Iāve got maybe 50% success ratio in training mode. Havenāt even attempted it in a match yet. I get so jealous when I see these pro players hitting it every time like itās not even a big dealā¦
LK SBK After EX kikoken midscreen is max damage for 1 meter. Donāt feel bad about it. What youāre doing is correct. 
Iāve gotten much better at it with more practice. I can do 90% of time in training and about 75% of the time online. Thereās a certain rhythm to it. Once you figure that out itāll be much easier to do consistently. I generally know when I donāt have the charge so I just cancel into legs sometimes.
My issue now is doing the low instant air legs consistently.
I would try the āspdā motion for it if I were you. Essentially, you go to up-forward, then go backward until youāve come nearly full circle to forward. So, facing right and starting at 5 (neutral), that would be 98741236. Iāve been trying to implement that method more often because it makes sense to me and is pretty consistent.
Iām so excited that I can do her Cr LP > St MP > Cr MK > SBK combo almost 90% of the time. It does take practice, but they two most important things to remember when executing her combo is
- Crouch the moment St MP is thrown out. Donāt do it too fast or else youāll end up doing her Cr MP. Donāt do it too late or else there wonāt be enough charge. This step was always the hardest step for me.
- Execute her SBK the moment the Cr MK leg seems like itās going to pull back. If youāre jumpy with the SBK, she wonāt perform it. It really is a last second execution. You feel like you should execute the SBK the moment of contact or after a hit confirm, but the trick is to wait the last second of her active animation. The momenet Chun-Li pulls her leg back from the Cr MK animation is where you execute the SBK.
The best visual cue for Cr. Mk xx MK SBK is seeing the hit counter add the Cr. Mk.
Upon seeing the hit counted it is easily reaction canceled into SBK
After a 10 or so minutes of doing that you shouldnāt ever have any problems doing it.
I can get the st.mp>cr.mk and cancel late enough to get the spinning bird kick to come out, but I almost always cancel too late and the medium sbk doesnāt combo.
You can cancel into lk sbk much later than mk sbk, so if youāve been using that combo to get started then you have to adjust to building the charge as soon as you hit mp, and then canceling the mk into sbk sooner so that it has enough time to connect and continue the combo.
Apologies if this has already been said (I didnāt have time to go through 4 months of comments)ā¦but I wanted to let those who didnāt know that after a jump in, or instant air legs - instead of c.lp, st.mp, cr.mk xx mk.sbk, you can just do st.lk xx lk.legs, cr.lp xx lk.sbk - the damage is 1 point less than the other combo, and much easier to hit. The only thing is that you get less stun.
You donāt get a knockdown thoughā¦
You do get a knockdown with any SBK, the only downside to the combo I mentioned over the other is the amount of stun you do. Its like the combo in this video, and you can start it however you want (not just crouching fierce), whatever you do to get to lk lightning legs, you go crouching jab and then light spinning bird kick.
Youāre right man, i read it wrong. My bad. :s It really is a good idea and its very easy to do!
No need to apologize! It is true though that you should learn the cr.jab, s.strong, cr.forward xx SBK comboā¦while it does one less damage, the stun you get is worth it and in learning how to consistently hit it, you will be optimizing your character. I had to practice it for about two weeks, and I still miss it sometimes.
I found that holding down after you press cr.jab a split second longer before releasing and pressing st.medium punch, then immediately holding down again helps - you also have a bit more hit stun after st.medium punch than you think, so wait as long as you can to hit cr.medium kick and then double tap medium kick when you cancel the SBK at the end.
The way SFV inputs are setup, you should be holding down after you hit st.medium punch before the animation for it even starts.
Yup, iāve done it many times in training mode but my crappy execution stops me from doing it in a real match. Thanks for the help though.
I have more trouble in matches too - but I think itās because the adrenaline gets pumping and I start playing ātoo fastāā¦inputting commands too quickly. Most of the time in this game, I think, if you have an execution error itās because your doing it too fast.
I woke up in the morning one time and started playing right awayā¦I didnāt mess up one combo or instant air legs once. I have to remind myself to slow down.
Is it possible to perform IOH stomp on pad? If so any tips?
I play on padā¦itās just the same as you would do it on stick I would imagine. I jump and immediately hit down and kick. I canāt get it to cancel into air legs like other people can thoughā¦not sure what the trick is there - seems Iām well past the height requirements. But the stomp itself is just jump, and immediate down+kick.
