Get the strap around the tree high as high as you can.the top of your head or higher.As long as it is tight when you sit down it will be high and out of the way when you draw. I've found that by doing that you draw underneath the harness when you are rotated to the right. Plus, it puts the harness in the guidelines of the TMA.

When the tree strap is around my shoulder area or a little lower I always get caught in it drawing the bow.
