Explanation of the loft x directional accuracy relationship

In the previous post, I wrote that the lower lofted clubs will produce "straighter" shots. What I meant was close to that. It's not the trajectory; the greater the loft angle, the more backspin vs. sidespin, and the less bend in the trajectory -- less hook and slice.

But -- and this is very much a concern -- The ball will always fly off the face of the club perpendicular to that face. If the sole of the club is parallel to the ground, then the shot will leave the face pointed toward the target. If the toe of the club is higher than the heel, the ball will start out more in the direction of the heel; if the heel is elevated, the ball will begin its flight toward the toe. 

For a right-handed player, if the ball is higher than the player's feet, the tendency would be to pull the ball to the left; lower than his feet, we tend to push to the right.

The greater the loft, the more severe the deviation of the initial flight.

And so, in the end, the lower-lofted driver is more likely to send the ball in the direction the face is aligned.
