K, S, S, 2HS(1hit), 236+K etc... is all right, but deals small damage. (the good thing is that the timing is so easy, that it's almost impossible to screw it up..^^)
I would recomend that over mine above when you are SURE that it will finish the opponent off.
EDIT: OH! but what you can do, if you manage to JI in between the S, S, you can RC the 236+K into a JS and air combo directly without touching the ground.
makes it like: K, S, JI, S, 2HS, 236+K, RC, JS, P, S, HS -> 3 kicks (off course, that a little bit more tricky to pull out)
another thing you can do is to RC on the 623+K into an air combo.
K, S, S, 2HS, 236+K, 623+K, RC, JP, S, P, HS -> 3 kicks
well, this is what I use, as I find the TK236+K almost impossible to perform and completely useless as 95% of the time, your opponent will be crouching and the TK236+K will NOT hit!
