A+B is completly safe. 33B too, and it leads to the same combo. But someone else should check it too.
Lolo posted this last page, but you should add A+B, 66K to the first post. It's 49 damage (only 1 less than 44AB), but can wallsplat.
You might wanna change the yellow ones to something else.. I'm using the ExMachina Light forum skin and they're practically invisible.
