Struck Animation Without Facial Animation

I have completed the movement of the body for the final version of my struck animation, without the facial animation applied yet. I was having trouble with the first 0-5 frames however, where the staff would pop back and forth out of place. I know the reason why it was happening, the pivot point on the staff forces me to translate the staff when I do a rotation in order to keep it in the same place on the floor space. I applied a euler filter in order to resolve the issue but it made very little difference, probably because the error occurs within the first 3 frames, which is difficult to manipulate within such a small time frame.

I finally smoothed it out as much as possible by manipulating the rotation tangents in the graph editor. It's not perfect, but it is cleaner than it was, and with it being only 1 or 2 frames where it takes place it doesn't take much away from the animation in respects to the principles of animation. For example the weight I tried to represent in the staff is still preserved, as well as follow through actions, timing, exaggeration and arcs.

Original version:

(note: closely watch the bottom of the staff at the beginning frames)

Cleaned up version:

(note: closely watch the bottom of the staff at the beginning frames)

All that is left to do is apply animation to the face and eyes.
