If you are in the corner they actually bounce back too fast, B sledge comes out pretty slow and moves pretty far. I've landed 5D into 236B a few times today on various characters who ate a CH 5D
But I didn't Exactly know how to combo from it, I think I tried to do 5D, 236B, 5C, 623C, 6C, Shot, 2C, 623C. On Tao you can probably omit the Shot, 2C like usual. I would.
Might be situational, a lot of these guys were trying to airdash at me when they got slammed
