I wonder about swing speed and "roll"
 

When a golfer's swing speed is measured I wonder if it can account for the "roll" of the clubface into impact? I bet not.

It seems to me that if the clubhead is moving at 100mph AND the clubhead is also ROLLING to a square position as it approches impact, that this ROLL would create additional speed.

Pondering in Austin....

Don't know the science or figures. But there has a mechanical advantage in terms of speed of having the shaft inserted at the side of the clubhead rather than the center. It's another lever.

If the sweet spot is moving at the same speed, the tip of the clubface will move faster and the heel of the clubface will move slower with horizontal hinging compared to vertical hinging.

And what you want to find is the point where you 'keep up'.

That will be the 'heaviest' roll
That will be the 'smoooooothest' roll
Your hands will be 'set' without 'doing'

Just add a 'little' twist...... and 'keep up'

Let Extensor Action be the 'limit' of the 'twist'
