I think I'll try refletching half of the GT's to see if they fly better with helical. If that still doesn't work, I'll take some weight off of the bow and then if needed try paper and bare shaft tuning to see if I can fix the problem. If I still don't notice a difference, I'll throw away my Mathews and go buy a Hoyt!!!(As opposed to getting some shooting lessons)<img src=icon_smile_wink.gif border=0 align=middle>
