I understand the concept of the arrow holder on the shelf which does not necessary have to line up with anything. I guess what throughs me is that the arrow in the particular picture that I was commenting on looks to be lined up in the groove of the arrow rest. I understand that the arrow rest will move vertically upward during the draw cycle. What I didn't know was that it will also move horizontally.

In the past I have used a Golden Key Premier Drop away which only really moved vertically. It also locked in the up position, so there was really no arrow travel in the drawing cycle.
