Over the past 3 or 4 years I have had an infestation of the shanks. As Yoda stated in an earlier post it was due to being off plane. The laser tool that KevCarter threw at me worked great at providing a much better concept of plane.
As a result of that I have also found that a strong pivot and focus on the aiming point help greatly in getting the club on plane and making a good pass.
