For those of you still breaking backs, I dont know you all remember the psuedo otg command grab set up off F2D3 where you dashxxgrab after and you cannot jump or backdash the grab you can only wake up with invincibility to get out, but you can also do the same thing with super and not backdash or jump it....
Also I swear i tried to side switch off B23 by dashing under hundreds of times originally but i finally got B23, dash under D1 to combo. Unfortuneately D1xxcommand grab whiffs but D1 xx double punch works, forgot to test uppercut
