Just take a longer than normal arrow and wrap a bread tie around it , draw the bow a couple of times and simply slide it to the length you want the arrows to be. Then measure the distance from the throat of the nock to where you want them cut..........that's the length you want to order.
Why guess?
Im wondering whats there "supposed" to be, like i heard someone say take your draw lenth and add 1.5 inches.
