I use 2" blazers and have always only been able to fletch them about 2-3" down from the nock. I got an oldfletcher my dad had and can now fletch them about 1/2 inch down. Was wondering where you guys like to fletch your arrows at? Down the shaft a couple inches or as close to the knock as you can? Also theveins closer to the knock seem to make the arrow fly better from what I saw.
