I haven't done much testing with various DIs and percent ranges, so take these with a grain of salt.
D-throw-> Footstool-> Sweetspot Dair Jablock-> Sliding Rock Smash (49%)
D-throw-> Footstool-> Sweetspot Dair Jablock-> Sliding Rock Smash (49%)
- works without sliding rock smash, but more consistantly deals max damage with sliding rock smash
- may be escapable after the first Fair; like I said, I didn't do much testing
