OK here's video of today's hitting session. Was trying to emphasize internal shoulder rotation and flattening out the swing path. Wasn't too successful judging by the video, but the shots were definitely hit with better pace. I hope the wrist thing has been minimized already...
Am loving this Kinovea software! Slow mo vids below:
Slow motion vid from front/side. Should the swing path be flatter still...say 20 degrees?
Slow motion from rear.
