Don't use 5K unless she's REALLY low on the wall and you're actually close enough for it to connect. She floats really high so you have to use 2H > 6HH instead of 5K > 2H > 6HH.

Use either one or both hits of 2H depending on how high she is and where you are in the combo. Usually it's a safe bet to just use 2H(2).
