got to check out the new Goldtip line up today and saw the new Pro series arrows. They have a .001" straightness and +or- 0.5 grains. I've been told you can re-order arrows to a code number to get the exact same weight with each dozen you order in the future. Can wait to try them out. I think they are releasing them at the show next week with the new broadheads. Web page will show them soon.
