I recently started working these with one of my level 8s. She has a beautiful toe shoot to high and a free hip handstand so I thought they would be easy, but she couldn't get it. We've only done one practice, but I'd like to have her learn it as fast as possible. She seems to fling her feet off the bar when she gets underneath it, but only when going from a cast handstand. I've told her to push her feet into the bar, but I don't know what else to say.
