straight feathers vs. helical

I shoot three, five inch shield cut feathers and for lack of selection locally i bought a bunch of five inch parabolic feathers. I generally fletch my feathers almost straight (left wing). this time for fun I put more twist or helical on the first arrow that I made up and found that it has terrible flight. Is it because I switched to parabolic or put more twist in the feather. Tomorrow I will glue the parabolic feathers on straight and get to the bottom of it. Anyone have any experience with this?

Thanks,

DK

Are the parabolic feathers left wing? Did you use a helical clamp or just put more offset on the feather?

Yes the parabolic feathers are left wing and the clamp is a helical clamp.

Doug –

Can you give a little more detail about how they are flying, or why the flight is ‘terrible?’

There should not be any difference in flight between a parabolic and shield feather. Adding helical usually improves flight. You said both feathers are LW, is the helical clamp a LW? You are using a LW helical clamp and not just offsetting a straight clamp more?

I agree with Raghorn. Any difference between parabolic and shield would be minimal (I shoot both). The helica should improve flight with broadheads and I have never head of it hurting field/target points.

Used to was target arrows were straight fletch as helical robs some speed.
