Simply controls the clubface and gives you instant feedback if you do it wrong!
You cannot twist it, tilt it, add/decrease loft or lift it up and down without knowing you did something wrong!
The key piece to control is the Training Trident that sits against your body.
When it stays in place you can't twist, roll, lift, or add/subtract loft
