I started messing around in training mode last night, and found out the HHS, HBxxSuper combo on Honda isn't actually that hard. All you do is mash a little bit after the HHS, then it's just a one frame link like usual. The hardest part about these combos is figuring out exactly how much mashing to do. Too much, and you won't recover quick enough for the next move, too little and you'll recover before the last hit.
