I saw an infomercial on Mr. Leadbetter's new aid...The Swing Setter.
It LOOKS as if all of the people on there were cocking both wrists, and DOUBLE COCKING the left wrist... at the left arm parallel to the ground position. Most LOOKED to be DOUBLE COCKED at the TOP or END also.
Do you think it is possible to get into the position Mr. Leadbetter wants at 9:00 or Left Arm Parallel to the Ground on the backswing, without cocking BOTH wrists?
The aid is also supposed to help with the "Release".
