A combo you can use if you see your second F2 was done too early and you risk dropping the combo. The tracking in that case goes bonkers and you must move a bit in order not to be facing the wrong side.
Walking back has startup, walking forward doesn't but tracking is horrible and gives mixed results, best of which is you land 1 ~ b14 air throw b14 whatever ender which causes you to lose a third F2's worth of damage.
