I don't know if you know this, but you know you can go from a special to a super/ultra really easily?
For example: Flash kick to Super flash kick (I forgot what it's called lol...)
You charge db (down back) then press uf (up forward) and kick. This will hit the flash kick, then because you already did the charge for the flash kick, you don't need to do it for the super flash kick. So from the first flash kick, you press db, uf, kick. If you do it right, you'll pull off the super.
You can do this with the qcf (quarter circle forward) moves too. Hadoken to Shinku Hadoken. You do qcf and punch, then do qcf and punch again. You don't have to do the second qcf in the Shinku Hadoken.
I hope that makes sense? lol...
