Get a hockey stick....hand it to your wife or somebody that has no clue about golf....watch how the move the stick...with the "square" shaft there is no tendency to load the hockey shaft for Swinging...the blade of the hockey stick will be "shutty" locking...the right forearm will move "in line" with the shaft...there will be no swivelling and the face will stay "square" to the plane....work with the hockey stick and you'll learn how hitting works...
Serious drive loading here....right arm participation (left arm in this cat's case)....angled hinging layback....HITTING.
