Nice article, I liked this quote:
"Achieving a level or even upward angle of attack is not the same as hitting "up" on the ball. It is important that your hands be in line or slightly ahead of the clubhead at impact. Note I said "clubhead" and not the ball. There is a big difference. In other words, you never flip your hands at the ball in order to increase your angle of attack, rather, you need some spinal tilt away from the target to achieve this position."
I think sometimes I try to hit up on the driver and I have a little flip which sends me to the left.
