I found out today that you can 6B after an air throw if it is near the ground and follow with dash 5B(2)
air throw, 6B, 66, 5B2, 5C, sekka, 6C, C car - 3006 dmg
the old bbcs2 corner air throw combo works but is a lot harder to land - 3683 dmg
air throw, 6C, 66, 5C, 6C, C dp, 5B2, 5C, 2C, C dp is easier to land and lands if you are a little bit away from the corner - 3491 dmg
