Edit: Ah, your post has been edited so now I have more to go on.
-Sweep: I only use this when I feel like I’m making Guile look like he has qcf commands. In which I mean I’m bringing the rush down. Sonic Boom, c.:lk:, c.:lk:, s.:lp:, Sonic Boom, Sobat, c.:lk:, c.:hk:. Most of the time I’m so in the zone, even if the opponent blocks the sweep and tries to counter I’ll Sobat out and throw a Sonic Boom again. You can probably throw a target combo in there somewhere. Hell, sometimes if the rush down juice is flowing so good, I’ll do TWO target combos back to back, c.:lk:'s, Sonic Boom, sweep. Hell, let’s just say I throw sweep out there when I got a good thing going and don’t feel like buying charge time using c.:lk:'s and such, because that can be boring and it’s fun to experiment!
-Sweep [part 2]: When they jump in from afar. Sure a Flash Kick could probably hit them, but it will most likely trade. And trading sucks. If you sweep when they land, you can have a chance to knock them down. If that fails, Sobat out!
-Flash Keek: If THEY Flash Kick from a distance, you should already have a Sonic Boom on hand and ready for that ass when they land. If you don’t, see if you can tag them with a Backfist. If they’re literally across the screen, that shit NEEDS to be punished by a Sonic Boom. Hell, EX Sonic Boom if you have it. And if you miss the perfect time to tag them with a Boom, throw one anyways [if it’s safe]. Build that meter and keep them out.
If YOU want to Flash Kick, then I would only suggest Flash Kicking when they’re jump in seems like it would land outside of c.:mk: distance. Anything closer should be dealt with c.:hp:. It’s amazing how more reliable that move is.
-Jab Cambos: Have that EX Flash ready for a possible jump away or jump in attempt. If you’re getting pelt by jabs, I would hope your blocking, and crouch blocking at that. Which means you got that charge on lock for either a Boom or a Flash. Also, as a finishing note: Abuse the target combo if you can. Target Combo, Target Combo, Sobat, Sobat, Sobat, BOOM!
