Well I just refletched the entire dozen with 4* right helical ( a littles good, a lot is better, right? ) except 1. WOW!! I shoot into a black target w/ white vanes and those things spin like you can't believe!!! I bet you could put a hatchet on the end and shoot it straight!! The one I didn't fletch w/ helical I fletched dead straight (just to satisfy mine and others curiosity). Shooting into the black target, it spun very quickly (visually it didn't seem to spin any slower than the 1/8" offset). It also shot the Snuffer that was on it very well. Well within a 3" bullseye w/ a dozen or so shots. Based on that dozen shots, I bet I could put it in the quiver w/ the 4* helicals and not notice a thing. I know from experience that AAE fletched straight do not shoot a snuffer this well.
