Hmmm... interesting. Which character are you testing it on? Maybe it doesn't work well on some of the cast. I was hitting the wallbounce combo about 80% after half an hour of practice vs. Noel. I don't recall trying it with Bang or the opponent in the corner though.
You're right though, it seems situational. In most cases, other options like the B&B combo off of 2A are a better choice, mainly for the free seal, and because it puts you in a better position.
Though, assuming it works on characters that tear Furinkazan apart like Nu or Arakune, it would be a nice alternate B&B combo. Though, like I said before, I couldn't get the final aerial double-palm to hit on Nu, but that could just be my execution.
Thanks for the info on the throws. I guess it's a good trade giving it such a high window to tech, since they don't scale.
The 5A reset sounds interesting, I haven't run into any info on command throw resets yet, I'll search around.
