One thing about helical, it's either all or none. A given helical clamp can only attach a fletch one way to your shaft. There is no adjustment. To change the amount of helical, you have to change the shaft.
I resprectfully disagree with that statement.The bitz is adjustable. The clamp has acertain amount of twist, which is not much, but adjustment of the jig is where you get more twist. I never put this hard of a helical on arrows. Even though I use EZ fletch grayling, and bitz. Iusally only use the EZright helical.
I would suggest that perhaps you are both correct. The clamp is the clamp and is set a certain way but I think by also
offsetting the helical clamp you can gain the appearance and the effect of a more helical fletch.
I have fletched vanes the you have them fletched here and, although I was not measuring for a speed difference, I measured speed on arrows with an offset blazer and arrows fletched like yours. If my memory serves me correctly they may have only been a couple of FPS difference and that just may have been other factors.
