I think I am somewhat following you but am personally unfamiliar with the cam on the Quest bow. I am assuming a dual cam bow since you have two diagrams. In which case, if you hook the string closer to the center of the cam then, normally, you are shortening the draw length. Moving outwards towards the edge of the cam normally lengthens draw length.

Are there any modules on the cam? If so then you should be able to place a new module in there to shorten the draw length. Most of the Fred Bear/Jennings cams have been designed in this manner for several years now.

Hope this helps.
