c4extrem,

AMO drawlength is measured from the apex of the bowstring to the throat of your grip (the deepest part)at full draw and then add 1.75". The length of your arrow doesn't matter too much, this is because of the placement of your rest and the setup of the bow. For example, I shoot a 29" draw, but a 28.5" arrow and could cut off about a half inch more if I wished. The Easton drawlength arrow is a good tool, but is generally used with fingers. It will get you somewhat close, but I think the wingspan method is better. The distance between your fingertips at shoulder height, minus 15" divided by two. This method will get you close, but there are some variances for your individual body shape.

Aim Hard!
