the Game Tracker Terminator 6075 I bought from Walmart flys perfectly with my Muzzy 100 3 Blades. I shot it 3 times from 20 yards and got about a 1" group with the practice blades on(hitting same spot as field points). When I shoot my gold tips (XT 5575)I seem to get more sporadic flight. The arrow actually looks like it makes a big sprial on the way to the target. The Goldtips are about 3" shorter. When I bought them, the guy who sold them to me just had me draw back and he made a mark on the shaft where he thought they should be cut (Just in front of the whisker biscuit) I guess my question is, could the shaft length be affecting the flight of my arrows, or is it just an improperly tuned bow? It seems to me that there should be a more systematic way for determining shaft length. Also, the Game Trackers have helical fletchings whereas the Gold Tips do not. I'm shooting a Mathews Legacy with a 30.5" draw and 72lb draw weight. Thanks for your help.
