Hmm, from just normal jump height, I usually just go Air Dash H > MHS and then air combo into whatever. I usually like trying to combo into Killer Bee so I can go for Strider assist combo extensions. You could also do Air Dash H > MH Volcano, but that's not too reliable if your opponent's too high I think. Doing MH > Cold Shower > Prop Shredder is also an option if you don't mind decreased damage.
