RE: Too much Helical?
I’ve had some pretty good debates with aero space engineers regarding the drag a helical fletch effecting momentum, vs. the increased spin caused by the helical creating a better air cushion to fly on and a more stable arrow. In the average hunting yardage from 20 -40 yards the difference is minimal….The bottom line in any case is the more helical you have the quicker you are going to stabilize the arrow flight. I liked the low profile 4 inch vanes with a lot of helical myself.[/b]

Especially with the heavier the arrows typically used in traditional archery the bigger feathers with more helical is definitely the way to go. These light fast flying carbon arrows are effected by wind and resistance more so than a heavier shaft, that’s why those little blazers are so popular. But I still preferred a longer low profile with helical over an off set vane….better arrow flight in my opinion.[/b]

I did some serious field testing using these quick spin arrows on a speed bow shooting over 300 FPS…. The increased spin carried those arrows further on a flat trajectory than blazers do by a significant amount at 50- 60 yards…..at 80 yards the momentum was starting to bring them closer together again due to the drag and extra weight of the heavy fletching….and at a 100 yards there was no elevation difference at all, but I was more accurate with the quick spins. The quick spin vanes did excellent in high cross wind conditions too…..a huge difference….. food for thought…Kirk[/b]
