With the longer clubs, my downswing thought is to start by turning the shoulders & upper body towards the hole, a la Jim "One Plane" Hardy. With the wedge I found myself starting the downswing with the arms, resulting in the right shoulder going onto the outside. When I do this with the longer clubs I get a pull or a slice. Easy to understand why this is a pull with the shorter clubs.
Works on the range, we'll see how it goes on the course this afternoon.
