err, secrets of Honda your asking there. jumping d.mk(splash) is nearly always preferrable over j.lk. With j.lk you have to be a spot otherwise you’ll get thrown for your trouble. As with the splash its easier to connect your stored oochio. If not you can just tap out a MP HHS for chip. j.lk can be quite usefull against guile’s sonic boom cause its so thin.
Getting through fireballs is probably one of the hardest things you’ll need to learn with Honda. At long range you can buttstomp and land pretty safe even with the mk version, be careful of sweeps though. You could even bulldog your way to mid range, (walk forward and block fireballs at the last second. I would strongly reccomend against buttstomping from this range, way to easy for you to be punished. What you can do is do a straight jump up HP, as you have slight control over it, and buffer it into HP HHS when you land, you’ll leap forward, and will either trade with the next fireball in your favor, or hit them clean. When you do get a chance to jump forward, you’ll prob just manage to make em block a jumping HP or HK, which you should also buffer into HHS. As they reel backwards from being hit or being pushed back by blocking you can gain some ground, you want to push them to the corner. Cause once you get one knockdown in the corner it should be game over.
