David, what is the draw length of the bow in the picture? I think that draw length looks to be at least an inch or more too long. But it does depend on what you want to do. For 3D shooting many people learn to shoot with a draw length that is a little too long because you will lose around 12 fps for each inch of draw length. But if speed is not the primary concern and utmost accuracy is then most people are better off anchoring with the string near the corner of their mouth and the bow arm should not be completely locked straight.

You are not the only one, I shoot about 26 1/2 to 27" inche draw length, but before I knew what I was doing I was shooting 29 or 30 inches. I shot OK back then but it was many years ago and I can't even imagine trying to shoot it now.
