HSS is a dual karate chop;so,your wrists hinge on the plane of the swing. Look at Jason Dufner's waggle (not his swing.) Notice how he takes the club on an inside path with the waggle? Instead of a one-piece takeaway, start your swing by hinging your wrists back/inside on the plane of the swing. Once you have moved about 1/2 of your wrist hinge to the inside, start your shoulder turn and continue to complete the hinge as your move to the top of your backswing. This initial move also helps preset the wrists into the 6/100 position for impact with the HSS. This move stops me from the violent hooks that can come with HSS. I still get an occasional pulled shot,but no hooks.
