Oh, and the best way to determine your draw length is to mark your arrows with different colored tape beginning at about 27" out to 29" or so. You can use 1/4" or 1/2" increments. Then have someone watch as you shoot and record the color of tape that is at the back of your riser when you release. Shoot naturally and don't try to over draw. Shoot a few arrows this way and have them kind of average it out. For most of us, this is a good method. Often you will find you don't draw as far as you thought on a consistent basis.

Tune your arrows to how you shoot. That's more important in the long run than how far you draw.
