For the fishermen, it's amazing how some things never seem to make sense until their casting techniques are exposed. And when that ball gets to the bottom way before impact position, this gives immediate feedback where power is lost. It gets the juices flowing. Power release requires and demands that the wrist cock is delayed. If there are distance issues, this is worth a try.
My favorite of the three is the pure swing, followed by angle pro (freaking funny watching your friends trying to set their right shoulder in the guide and also their expression with proper feel position ((extensor))at the top,,, and I am impressed with how good they look), then power release. All three have value and can provide feedback for improvement.
Of the three, my friends want to steal the power angle pro...
