I put into practice the keys that Greg posted and I felt a ton more stable. What was the most interesting to me was that I have been doing a push jerk instead of a split jerk this entire time. Switching to the split jerk was easier than I would have imagined.
I am going to shoot some video this weekend and I will post.
Last question I have really long arms and I am struggling with how far apart to place my hands. I have played with several positions my pull and squat feel better the closer my hands are and my jerk feels better the further apart my hands are. Should I just split the distance and go with a middle position? Right now I put my open hand on the bar so that the knurling starts directly under each thumbnail. That means my hands are about 2 inches in from the knurling.
