I know a few of you guys picked up BloodRunners from us already for this fall, so this may pertain to you. If not, spread the word anyways. I whined enough to the guys at NAP that they finally came out with a practice head. One small step for man, one giant leap for mankind. http://www.bowhunting.com/blog/post/2009/09/03/NAP-Introduces-the-Bloodrunner-Practice-Head.aspx
My complaint was no replaceable blades, I can practice with a hunting head. Appreciate your hard work as always though
