Yeah. On 2D you're really going to be better off just jDing it, 90% of the time. There's so much that can go wrong. Or, if you really can get it to work every time you try, please show me the timing on XBL sometime. Flashy combos are good times.
Also, I don't know if I posted this, but a way to hit Daifunka on 5D without 100 meter;
5D sjc.623B > 2B 623B daifunka
Works on all but Carl, IIRC
