There's another option that no one seems to be mentioning. In Toryuken 4 top 8 Reo vs Gunshow, Reo would sometimes take the last hit of 21122 to get knocked away for minimal damage and would not have to guess between grab, sand grenade, etc. Obviously your opponent could read that you will do this and just cancel sand grenade at 2112, but its another viable option that you should think about. The grab combos after the final 2, but if they cancel with sand grenade you get out of pressure and EB wastes a bar of meter.
