623a(2) > CS > 2C > j[C] > xxx works as well. You need to delay the 2C a bit to get both hits depending on your CS timing though. Another thing I was messing around with is.. rising jA > j214A. Depending on your spacing the j214A will hit on the other side. I don't think it's super useful or anything, but against someone with no reversal it's fun to do at the very least.
