My favorite change is the sweep range. It seems to make everything more reliable and it means you can get more damage meterless.
For example, dash momentum 2K > 5S > 5H > 2D works against everyone (?), and if you have an S dolphin set you can hold the 5S and end in H horizontal dolphin > ]S[ > aircombo. That one does 170+ off a 2K starter IIRC.
And for wakeup throw there's 5K > 2S/2K > 2D > etc.
Also, I'm a scrub so I like to use her 63214S super instead of RCs. It used to drop after a few hits if you tried it from sweep, but now a max range 2D > 63214S carries the full duration, and if you end in corner (which you usually do) you can end in 2H > vertical dolphin for hard knockdown.
