If you keep your right arm straight in the takeaway you'll find that when it starts to fold it will do so at the correct angle (i.,e 90 deg where your right elbow is pointing to the floor). If you dont your right elbow will be pointing somwhere behind you which is a bad position. This is what im trying to really work on at the range this winter. I also find for width you should have a slight lateral slide at the very start, to curl into your right leg. This also helps me get my hands further away from the ball (but make sure you keep the right knee flexed so as that move doesnt turn into a sway)
