PVchick - straight poling into a sand pit while gradually raising your grip to control your forward rotation -WHILE EMPHASISING A STRONG BODY AND COMPLETE EXTENSION OF THE TAKE OFF LEG AND ANKLE - from 2/4/6 steps only - is definitely the way to go. If you start gripping too high for safety in a sand pit - move to the box and pad and repeat off the short run. This way you learn to take off properly -which every sensible person who posts on this site will tell you is THE critical element of good vaulting - using your own energy, not that of someone pushing you through -who will not be there when you compete!
The tap is never needed if you are gripping at the right height for a specific run up. Just start with a low grip and gradually move it up -perhaps a hand grip at a time or 3 fingers/2fingers/1 finger. If you rotate forward quickly go up a hand grip then as the pole rotates slower move up only one finger until you know you are maxing out. Mark your grip height with a strong elastic band so you always know where you are. Measure the height you can get to off 6 steps and keep it as a record to improve each session. As it does so, your take off is improving.

Suggest to your new coach that they buy a copy of the "Beginner to Bubka" book. They will find many of the answers they need in there.
