pinwheel is absolutely correct. anything added to your arrow will and should make it fly differently than a bare shaft, and if it doesn't then something isn't right. ive seen guys that took this to such an extreme that they weighed the amount of glue they use to fletch their arrows. which falls back to my previous statement, that anything added to an arrow will and should make it fly differently than a bare shaft. i was wondering why you don't paper tune anymore? i see you powder test for clearance but how do you set your centershot and knocking point w/o shooting through paper? shooting 40 yds to set centershot and knocking point seems to me to be kind of a prolonged and ultimately inaccurate way to do this. you can set a c/s and k/p shooting through paper from about 10 ft in about 10 to 15 mins...then move back to 20 yds and 40 yds shoot through paper again and see what you have. using the human eye at 40 yds to check arrow flight seems pretty flawed. although you'll probably have no problem seeing that your arrows aren't flying correctly, do you then have to guess at what to adjust and what direction...etc..etc? just my opinion, but ive never had a problem obtaining perfect arrow flight by shooting through paper. it is also my opinion that checking arrow spline is overkill....there are so many charts out there that are very reliable for matching draw weight, draw length, arrow wieght, and arrow length that you're wasting your time unless you just like wasting your time...LOL <img src=icon_smile_big.gif border=0 align=middle>
