However, I have a hard time understanding how the hosel rotates around the sweetspot-to-grip axis - especially with respect to the Robot-Fit golf club testing machine. I would like to read your explanation of how the clubface passively rotates to square by impact in that machine. Jeff. Jeff View Public Profile Find all posts by Jeff
