Any tips on the vault so that she doesn't pike anymore. One of the level 7's said she is reaching down, instead of out. Could this be one of the problems?
In my experience, the most common cause of piking is leaning too far forward on the board. Here are a couple things I would try:
1) Start the run a little further back (say 6 to 12 inches), forcing her to take a longer hurdle
2) Tell her to think about pushing the board forward with her feet as she hits it; this will cause her to get her feet in front of her as she hits the board.
3) Tell her to start lifting her chest in the last couple steps of her run. THis will help her keep her chest up in the hurdle.
