It really doesn't matter how you start your backswing, as long as you are able to get into the following position at the top. For right handers, the checkpoints include 90-degree shoulder turn, extended left arm, 90-degree hand hinge, and high hands (90-degrees between upper right arm and torso, and 90-degrees between upper and lower right arm).
